Hardware Guide » Software » Ukucutshungulwa kwesithombe sekhompyutha: ukuthi isofthiwe iziphatha kanjani lezi zinhlobo zamafayela

El ukucubungula isithombe sekhompyutha Sekuyisici esikhona yonke indawo ekuphileni kwethu kwansuku zonke, sithonya yonke into kusukela ekuthwebuleni izithombe namafilimu kuya kwezokwelapha kanye nokukhangisa. Emhlabeni okhulayo obonakalayo, ikhono lokukhohlisa nokuthuthukisa izithombe selibaluleke kakhulu, ngokuthuthuka kwesoftware nezinhlelo zokusebenza zamadivayisi eselula akuvumela ukuthi uguqule izithombe ngemizuzwana. Nakhu ukuthi kusebenza kanjani lokhu kwelashwa. uhlobo lwamafayela.

Siyini isithombe sekhompyutha?

Una isithombe sedijithali noma isithombe sekhompyutha Iwukumelwa okubili kwesithombe esidalwe kusuka ku-matrix yezinombolo, ngokuvamile ngefomethi kanambambili (esakhiwe awodwa kanye noziro). Imvelo yesithombe ingaba i-static noma i-dynamic, ngaleyo ndlela inquma ukuthi isithombe se-matrix (noma i-bitmap) noma isithombe se-vector, njengoba sizobona kamuva.

Kukhona izindlela ezahlukahlukene zokuthola izithombe zedijithali, njengokuskena noma ukuthwebula isithombe ukuze kwenziwe idijithali. Ingase futhi idwetshwe noma yenziwe kusetshenziswa izinhlelo, noma yenziwe kusetshenziswa i-AI noma ukunikezwa.

Futhi, kufanele wazi ukuthi lezi zithombe zekhompyutha ingashintshwa Zilungiswa kalula kusetshenziswa isofthiwe efanele, okusho ukuthi azishintsheki. Isibonelo, amathuluzi wokuhlela ahlukahlukene, izihlungi, ukusula, ukukhulisa usayizi, njll., angasetshenziswa.

Uma isithombe sesidaliwe noma sesishintshiwe, singaba njalo isitolo ngefomethi enikeziwe. Kunamafomethi amaningi ezithombe, ngalinye linezici zalo. Isibonelo, i-JPG, i-PNG, i-BMP, i-SVG, njll. Ifomethi ngayinye izoba nochungechunge lwezimpawu zokulondoloza kanye nokuhlela okulandelayo noma ukubuka.

Ngokuvamile, amafayela wesithombe ezigciniwe zinezingxenye ezimbalwa ezifana nalezi:

• I-Headboard: Igcina idatha njengezibaluli ezibonisa ubukhulu besithombe, uhlobo lombhalo wekhodi (ifomethi), njll.
• Isithombe kanambambili: Lona ulwazi mayelana nesithombe ngokwaso, okungukuthi, indlela isithombe esakhiwe ngayo ngokuma, imibala, njll. Futhi lesi sakhiwo singahluka kuye ngefomethi.
• ImethadathaAmafayela ahlanganisa nesigaba semethadatha, okuwulwazi olwengeziwe olungahluka kakhulu kuye ngefomethi. Isibonelo, lokhu kungabandakanya ukuzwela kokukala, idethi yokulungiswa, ukuthi ubani odale ifayela, ngisho nedatha ethile evamise ukusetshenziswa amakhamera edijithali noma isofthiwe ethile.

Izici zesithombe sedijithali

I-Las izici eziyisisekelo yesithombe sedijithali sihlanganisa:

• Isinqumo: Isho inombolo yamaphikseli akha isithombe. Ngokuvamile kuvezwa njengenani lamaphikseli ngobubanzi nobude, isibonelo, 1920x1080 px. Ukulungiswa kuthinta ikhwalithi nokucaca kwesithombe, ngokulungiswa okuphezulu okubonisa imininingwane eyengeziwe.
• Ukujula Kombala (Amabhithi ngePixel): Ibonisa ukuthi mangaki amabhithi asetshenziselwa ukumela umbala wephikseli ngayinye. Isibonelo, ukujula kombala kwamabhithi angu-8 esiteshini ngasinye se-RGB kusho ukuthi kunamabhithi angu-8 (amanani angenzeka angama-256) amele izingxenye ezibomvu, eziluhlaza, neziluhlaza okwesibhakabhaka zephikseli ngayinye. Ukujula kombala okuphakeme kuvumela uhla olubanzi lwemibala ukuthi lumelwe, lunikeze ukunotha kombala okukhulu nemininingwane esithombeni.
• Isikhala sombala: Ichaza ukuthi imibala imelelwa futhi ihlelwe kanjani esithombeni. Izibonelo ezijwayelekile zifaka i-RGB (Okubomvu, Okuluhlaza, Okuhlaza okwesibhakabhaka), i-CMYK (Cyan, Magenta, Yellow, Black), kanye ne-grayscale. Isikhala sombala sinomthelela ekukhiqizeni kabusha umbala okunembile futhi sibalulekile ezinhlelweni ezinjengokwakheka kwezithombe, ukuphrinta, nokuthatha izithombe.
• I-Aspect ratio: Isilinganiso esiphakathi kobubanzi nobude besithombe. Ingavezwa njengesilinganiso (isb., 16:9) noma njengengxenyana (isb., 4/3). I-aspect ratio inquma umumo nokubukeka okubonakalayo kwesithombe, futhi ibalulekile ekubonisweni ezikrinini nasekuqageleni.
• Usayizi Wefayela: inani lesikhala isithombe esisithathayo kusitoreji sedijithali. Ikalwa ngamabhayithi, amakhilobhayithi (KB), amamegabhayithi (MB), noma amanye amayunithi. Usayizi wefayela unomthelela ekusebenzeni kahle kokugcinwa kwesithombe, ukudluliswa, nokucubungula.
• Ifomethi yefayela: Icacisa ukuthi idatha yesithombe igcinwa futhi ihlelwe kanjani. Izibonelo zifaka i-JPEG, i-PNG, i-GIF, i-TIFF, nezinye eziningi, ezingaba ngumnikazi noma umthombo ovulekile, ocindezelwe noma ongacindezelwanga. Amafomethi ahlukene anezinzuzo ezithile, njengokuminyanisa okungalahleki (PNG), ukucindezela kokulahlekelwa okusebenzayo (JPEG), noma ukusekela ukugqwayiza (GIF).
• Imethadatha: Imethadatha iwulwazi olwengeziwe olushumekwe esithombeni, njengedethi yokudala, indawo, noma imininingwane yekhamera esetshenzisiwe. Imethadatha ilusizo ekuhleleni nasekuhlukaniseni izithombe ngezigaba, kanye nokuhlinzeka ngolwazi lwengqikithi mayelana nokuthwebula.

Lezi zici zibalulekile ekuqondeni nasekusebenzeni ngezithombe zedijithali, njengoba ziba nomthelela kwikhwalithi yokubonwayo, ukukhohlisa, ukudluliswa, nokugcinwa kolwazi olubonakalayo.

Izinhlobo zezithombe ngokusho kokuqeqeshwa

Ngokuya ngokwakheka kwesithombe nokugcinwa kwaso kungobo yomlando, singathola izinhlobo ezimbili ezibalulekile okufanele uzazi, njenge:

IBitmap

Un i-bitmap noma i-rasterIsithombe se-matrix, esaziwa nangokuthi isithombe se-matrix, isethi yedatha emelela igridi engunxande yamaphikseli anemibala noma amachashazi. Le matrix ingaboniswa noma ilungiswe, futhi idalwe kusetshenziswa isofthiwe yokudweba.

Ukulingiswa kwezithombe ze-bitmap kuvame ukwenziwa ngokuphakama nobubanzi bazo amaphikiseli (yize ingenziwa nangezinye izindlela), kanye nokujula kombala wayo ngamabhithi ngephikseli ngayinye. Ukujula kunquma inani lemibala ehlukene engagcinwa endaweni ngayinye noma ngephikseli. Okusho ukuthi, uma ukujula kukhulu, kuba ngcono ikhwalithi yesithombe, noma okungenani ukucebe kobubanzi bemibala esingaba nabo.

Kubalulekile futhi ukuqaphela ukuthi ichashazi ngalinye noma i-pixel eyakha i-bitmap iqukethe imininingwane yombala ngokuzimela, emelwe amashaneli ahlukene. Le mibala ingaba ngefomethi ehlukene, njengaleyo eyaziwayo RGB, CMYK, LAB, njll. Amanye ama-bitmaps athuthuke kakhulu angafaka ngisho neshaneli ebonisa ngale noma isendlalelo esinokujula okufanayo nemibala, okuvumela amazinga ahlukene okukhanya. Eyakamuva isetshenziswa kumafayela athuthukile njenge-PNG noma i-TIFF, njengoba amanye amafomethi afana ne-BMP, i-JPG, njll., awakusekeli obala futhi alula, avele abonise amaphikseli anombala ohambisanayo ukuze enze isithombe.

Izithombe ze-Bitmap zine Umkhawulo oqhathaniswa nezithombe zevekhtha ukuthi ubukhulu bazo abunakushintshwa. ngaphandle kokulahlekelwa okuphawulekayo kwekhwalithi. Zingakhuliswa ngokulahleka kwekhwalithi ebalulekile, futhi zingancishiswa, lapho ukulahlekelwa kungabonakali kancane. Ngakho-ke, isinqumo okwakhiwa ngaso i-bitmap sibalulekile. Kokubili ezinhlelweni zokusebenza zokuhlela nakumadivayisi athwebula lezi zithombe, ukulungiswa kungashintshwa kuzilungiselelo. Isibonelo, ungakhetha i-bitmap engu-512x512 px, noma i-bitmap engu-1280x720 px, njll. Lapho ukulungiswa kuphezulu, kuyanda nosayizi wefayela odingekayo ukuze kugcinwe isithombe, kodwa kuba mkhulu imininingwane esizoba nayo ngenxa yenani elikhulu lamaphikseli.

Ihluzo ze-Bitmap zigcina nje umbala wephikseli ngayinye ku-matrix engxenyeni yesithombe kanambambili yefayela, kanye nesihloko kanye nemethadatha. Ngalesi sizathu, ama-bitmaps asetshenziswa kakhulu ekuthwebuleni izithombe zedijithali nokudweba ezinhlelweni ezidumile nezinhlelo zokusebenza ezifana nePaint, Corel PaintShop, Krita, njll.

Ngaphezu kwalokho, kufanele kushiwo ukuthi lawa ma-bitmaps angaba guqula kusuka kufomethi eyodwa iye kwenye Ngokusebenzisa isofthiwe efanele, zingacindezelwa ukuze zenze izithombe zithathe indawo encane, okusho ukuthi zilula futhi zithatha isikhathi esincane ukulayisha, nakuba lokhu kungase kuholele ekulahlekeni kwekhwalithi ethile. I-bitmap ingabuye iguqulwe ibe isithombe se-vector. Ukuguqula i-bitmap ibe yisithombe se-vector kwaziwa ngokuthi i-vectorization, kuyilapho inqubo ehlehlayo yokuguqula isithombe se-vector sibe i-bitmap yaziwa ngokuthi i-rasterization.

Umfanekiso weVector

Una isithombe se-vector, eyaziwa nangokuthi i-vector graphic, iwumfanekiso wedijithali owenziwe ngezinto zejiyomethri, njengamasegmenti, amapholygoni, ama-arcs, ama-polylines, ama-ellipses, imibuthano, amajika e-Bézier, bezigons, umbhalo (I-TrueType noma i-FreeType), nezindonga, ngakunye kuchazwa ngezibaluli zezibalo ezinjengomumo, njll. Le engeli yekhompuyutha ivumela kakhulu izithombe

Ngakho-ke, sinohlobo oluhlukile lwesithombe kunalesi esike sasibona kuma-bitmaps, okumane kuyiqoqo lamaphikseli anolwazi lwawo lombala. Inzuzo enkulu yezithombe ze-vector yikhono lazo lokushintsha usayizi usayizi wesithombe ngaphandle kokulahlekelwa yikhwalithi. Ngakho-ke, isithombe singadalwa ngesayizi esinikeziwe bese silinganiswa kusayizi oyifunayo ngaphandle kwalezi zinkinga ezilahlekile. Ngaphezu kwalokho, zivumela ukuguqulwa okulula, ukunwebeka, nokuguqulwa kwezithombe. Lawa makhono abangelwa ukuthi awagcini amaphikseli nemibala yawo ebalazweni noma ku-matrix, kodwa kunalokho agcina ulwazi kumfanekiso kanambambili wezinto ezihlanganisa isithombe. Ngakho-ke, ukushintsha nje usayizi wemfanelo kuzivumela ukuthi zilinganiswe ngaphandle kokulahlekelwa.

Ngenxa yalokhu kuguqulwa, ihluzo ze-vector zisetshenziswa kakhulu ezithombeni Izinhlelo ze-CAD, yezithombe eziku-PostScript, imibhalo ye-PDF, yokudala amafonti e-TrueType, i-OpenType, i-PostScript, njll. noma izinhlobo zokubhala, kanye ne Imidlalo yevidiyo edinga ukujwayela usayizi wesikrini noma ukulungiswa, amawebhusayithi, ukukhangisa, ukuphrinta, amacebo okusika, imishini ye-CAM ne-CNC, njll.

Amafomethi wefayela lezithombe zeVector nawo angahlukahluka, njengasendabeni yama-bitmaps. Isibonelo, sinamafomethi athile aziwa ngokuthi I-SWF, i-SVG, ne-VML, phakathi kwabanye. Izibonelo zezinhlelo zokucubungula lolu hlobo lwesithombe zifaka i-Inkscape, i-InDesign, i-CorelDRAW, i-Adobe Illustrator, njll.

Okokugcina, kufanele kuqashelwe ukuthi ihluzo ze-vector nazo zingafaka izinto ezibonakalayo ezifana nama-bitmaps, nokuthi zinezinye. izinzuzo ngokuphathelene nama-bitmaps, afana nalokhu:

• Zidinga indawo yokugcina encane, njengoba ulwazi lwe-vector lulula, uma luqhathaniswa namabhithi namashaneli.
• Azilahlekelwa yikhwalithi uma zishintshwa usayizi, okuvumela ukukala okungenamkhawulo.
• Amanye amafomethi asekela ukugqwayiza.

Nokho, nayo inakho ukungalungi uma kuqhathaniswa nama-bitmaps, afana nalawa alandelayo:

• Azikulungele ukubhala ngekhodi izithombe zomhlaba wangempela noma amavidiyo, njengalawo ashuthwe amakhamera, izikena, njll.
• Idatha echaza umfanekiso wevekhtha idinga ukucutshungulwa, okunganciphisa ukunikezwa ezikrinini noma kumaphrinta. Futhi noma ngabe isithombe sakhiwe ngezithombe zevekhtha, isibonisi saso kufanele ekugcineni sihunyushwe sibe amaphikseli esikrinini noma esiphrintiwe.

Izinhlobo zezithombe ngokuya ngokucindezelwa kwazo

La Ukuminyaniswa kwesithombe Kuyinqubo ebalulekile ekuphathweni kwedatha ebonakalayo, evumela osayizi bamafayela ukuba behliswe ngaphandle kokulahlekelwa kakhulu ikhwalithi yesithombe, nakuba ukulahlekelwa kuncike ohlotsheni lwendlela yokuminyanisa esetshenzisiwe. Kodwa-ke, ukwenza isithombe sibe sincane noma ukuthatha isikhala esincane sokulondoloza kungaba nezinzuzo zokusetshenziswa kumawebhusayithi lapho ukulayisha ukwehlisa ukwehla ngenxa yalezi zithombe kungafiseleki, noma ukonga isikhala kumidiya yokugcina.

Phakathi kwezithombe ezinokucindezelwa singagqamisa amasu noma ama-algorithms like:

• Ukufakwa Kwekhodi Kobude Bokugijima (RLE): Kuyindlela elula kodwa esebenzayo yokuminyanisa izithombe, ikakhulukazi eziwusizo ezithombeni ezinezifunda ezinombala oqinile. Kule ndlela, ukulandelana okuphindaphindiwe kwamaphikseli kufakwa ikhodi ngokumela inani lephikseli nobude bokulandelana. Isibonelo, umugqa wamaphikseli amhlophe (255) esithombeni ungabhalwa ngokuthi "255, 10" uma kukhona amaphikseli angu-10 alandelanayo anenani elifanayo. Nakuba i-RLE iphumelela ezimweni ezithile, ukusebenza kwayo kungakhawulwa ezithombeni ezinokuhlukahluka kombala okuyinkimbinkimbi kanye nokuthungwa, njengoba ingahloli amaphethini ayinkimbinkimbi.
• I-JPEG (Iqembu Elihlangene Lochwepheshe Bezithombe): I-JPEG iyindinganiso yokucindezelwa kwesithombe esetshenziswa kakhulu. Ngokungafani ne-RLE, i-JPEG isebenzisa indlela yokucindezela elahlekile, okusho ukuthi ulwazi oluthile olubonakalayo lulahlekile, kodwa luvumela ukucindezela okwengeziwe. I-algorithm ye-JPEG isuselwe ku-discrete cosine transform (DCT) kanye nomthamo. Enqubweni ye-JPEG, isithombe sihlukaniswe ngamabhulokhi, futhi i-DCT isetshenziswa kubhulokhi ngayinye ukuguqula ulwazi lwendawo kulwazi lwemvamisa. I-Quantization iyenziwa, lapho amanani e-DCT encishiswa ukuze kususwe imininingwane engafuneki. Inani lokulahlekelwa lilawulwa yikhwalithi ekhethiwe phakathi nenqubo yokuminyanisa. Nakuba i-JPEG isebenza kahle kakhulu mayelana nokucindezela, ukulahlekelwa kolwazi kungabonakala, ikakhulukazi uma ukucindezela okunamandla kwenziwa. Ngaphezu kwalokho, ayilungele izithombe ezinezindawo ezinombala oqinile noma imininingwane emihle.
• I-PNG (Portable Network Graphics): enye ifomethi evamile esebenzisa ukucindezela okungalahleki. Ngokungafani ne-JPEG, i-PNG ilungele izithombe ezinezindawo ezinombala oqinile, ongafihli, nemininingwane ebukhali. Isebenzisa i-algorithm yokucindezela esekelwe ekubikezelweni nasekuhlungeni. Ku-PNG, uchungechunge lwezihlungi lusetshenziswa emugqeni ngamunye wamaphikseli ukuze kuncishiswe ukuphindaphindeka ngaphambi kokucindezelwa. Ukucindezelwa okungenakulahlekelwa kwenza i-PNG ithandeke ezimeni lapho ukwethembeka okubonakalayo kubalulekile.
• I-GIF (Ifomethi Yokushintshisana Kwezithombe): Yaziwa ngamandla ayo okugcina izithombe ezigqwayizayo, kodwa futhi iyifomethi yokuminyanisa esebenzayo yezithombe ezimile. Isebenzisa indlela yokucindezela i-Lempel-Ziv-Welch (LZW), ebheka ukulandelana okuphindaphindayo kwedatha bese ifaka amakhodi amafushane esikhundleni sawo. Nakuba i-GIF inikeza ukuminyanisa okusebenzayo, izifanele kakhulu izithombe ezinombala olinganiselwe, njengoba ingamela kuphela imibala efika ku-256.

Inqubo yokucubungula isithombe sekhompyutha

El ukucubungula isithombe sekhompyutha, ibhekisela kusethi yamasu nama-algorithms asetshenziselwa ukukhohlisa izithombe zedijithali ngohlelo lwekhompyutha. Lo mkhakha uhlanganisa izimiso zobunjiniyela, izibalo, izibalo, nesayensi yekhompiyutha ukuze kuhlaziywe, kulungiswe, futhi kuthuthukiswe izithombe ezivela emithonjeni ehlukahlukene, njengezithombe, izikena, amakhamera edijithali, ama-MRIs, neminye.

I-Las izinhlelo zokusebenza Lokhu kucutshungulwa kwesithombe kungasetshenziswa ngezinhloso ezehlukene, njengokuthwebula izithombe, ukuzihlela noma ukuzilungisa, ukukhiqiza izithombe ezinyakazayo, ukuzifaka emidlalweni yevidiyo, into engekho ngokoqobo, okwangempela okungeziwe noma okuxubile, njll.

Ngokuqondene ne amasu asetshenzisiwe Ukuze kucutshungulwe isithombe sekhompyutha, okulandelayo kufanele kugqanyiswe:

• Ukuthwebula isithombe: Izithombe zedijithali zitholwa kusetshenziswa amadivayisi wokuthwebula njengamakhamera edijithali, izikena, noma ezinye izinzwa. Lezi zithombe, zimelelwe njengama-pixel afanayo, ziyisisekelo sokucutshungulwa kwesithombe.
• Iyacubungula ngaphambili: Ngaphambi kokusebenzisa amasu athile, ukucubungula ngaphambilini kuvame ukwenziwa ukuze kuthuthukiswe ikhwalithi yesithombe. Lokhu kungafaka phakathi imisebenzi efana nokulungiswa kombala, ukulungisa umehluko, ukususwa komsindo, nokulola.
• Kuhlungiwe: Izihlungi ezahlukahlukene zisetshenziselwa ukugqamisa, ukuthambisa, noma ukususa imininingwane ethile esithombeni. Izihlungi zingaba yilayini noma zingaqondile futhi zisetshenziswa ngokuya ngezinhloso ezithile zokucubungula.
• Ukuguqulwa kweJiyomethri: Ikuvumela ukuthi uguqule i-geometry yesithombe, njengokuzungezisa, ukukala, noma ukuhumusha. Lezi zinguquko ziwusizo ekuqondeni izithombe, ukulungisa ukuhlanekezela, nokwenza ukulungisa kwendawo.
• Ukuhlukaniswa: Kuqukethe ukuhlukanisa isithombe sibe amasegimenti anengqondo noma izifunda ezinezici ezifanayo. Ukuhlukaniswa kubalulekile ekubonweni kwephethini, ukutholwa kwento, nokuhlaziywa kokuqukethwe.
• Ukubonwa kwephethini: Ama-algorithms okufunda komshini nezindlela zokubona zekhompyutha zisetshenziswa ukukhomba amaphethini nezinto ezisezithombeni. Lokhu kubalulekile ezinhlelweni zokusebenza ezifana nokubonwa kobuso, ukuhlukaniswa kwezinto, nokuhlaziywa kwesithombe sezokwelapha.
• Ukubuyiselwa kwesithombe: Inhloso ukubuyisela noma ukuthuthukisa izithombe ezithintwe ukucekelwa phansi, njengalezo ezibangelwa umsindo, ukuphazamiseka noma ukuhlakazeka.
• Ukuminyanisa isithombe: Ukucindezela kunciphisa usayizi wamafayela esithombe ukuze kube lula ukugcinwa nokudluliswa. Ama-algorithms afana ne-JPEG ne-PNG avame ukusetshenziselwa le njongo.
• Ukufiphalisa: Ukufiphalisa kuyindlela enciphisa ukucijile nemininingwane esithombeni. Lokhu kufinyelelwa ngokusebenzisa isihlungi esilinganisa amanani amaphikseli azungezile, ukudala ukubukeka okuthambile, okungachazwanga kangako. Ukufiphalisa kusetshenziselwa ukunciphisa umsindo ezithombeni, ukufiphalisa imininingwane engafunwa, noma ukudala imiphumela ethambile yobuhle.
• Ukugqamisa (Ukukhulula): Kuyindlela egqamisa imiphetho nemininingwane yesithombe, idale ukubukeka okufana nokukhululeka. Kufinyelelwa ngokugqamisa izinguquko zokuqina phakathi kwamaphikseli angomakhelwane nokusebenzisa izithunzi nokugqamisa ukulingisa ukubukeka kwezinhlangothi ezintathu. Isetshenziselwa ukuthuthukisa ukubonakala kwemininingwane ezithombeni nokugqamisa izici ezibalulekile.
• Ukulola (Ukugxila): Ukulola kuyindlela egqamisa imininingwane namaphethelo esithombe ukuze sicace futhi sichazwe kakhudlwana. Kufinyelelwa ngokugcizelela umehluko wokushuba phakathi kwamaphikseli aseduze. Ukulola kusetshenziselwa ukuthuthukisa ukucaca nokuchazwa kwezithombe, ikakhulukazi lapho kugqanyiswa imininingwane emihle.
• Umbala Wamanzi: Ilingisa ukubukeka komdwebo we-watercolor. Ithambisa imiphetho futhi ifiphaze imibala, inikeze isithombe ukubukeka kobuciko nokuphilayo. I-Watercolor isetshenziselwa ukudala imiphumela yobuciko ezithombeni, ihlinzeka ngesitayela esihlukile, esipendiwe.
• I-Convolution Kernel: Kuyisu elisebenzisa ukuguqulwa kwendawo esithombeni ngokuhlanganisa isithombe nge-matrix ethile (i-kernel). Isici ngasinye se-kernel sinomthelela ekuguqulweni kokuqina kwamaphikseli endaweni yawo. Izinhlamvu ze-Convolution zibalulekile ekusebenziseni izihlungi kanye nemiphumela ekucutshungulweni kwesithombe, njengokufiphalisa, ukutholwa konqenqema, nokuthuthukisa imininingwane.
