Iyo tekinoroji yeminwe yemunwe inoratidza kubviswa kubva kuMafingerprint mufananidzo muFingerprint Nguva Yekupinda Machine Yekudzora

Zvimiro zvemunwe zvinowanzoshandiswa neFingerprint Kupinda Machina ekudzora muCingerprint kuzivikanwa Iyo inobviswa zvigunwe zveminwe zvinoshandiswa kushandiswa kweminwe. Iyo kiyi tekinoroji inobatanidzwa muCingerprint Spect International Inonyanya Kuenzanisirwa Kuverenga, Core Freeptation Kuverengera, Kuwedzera Kweminwe, Kugadziriswa, node Kubvisa uye kusefa, uye kuongorora, uye kuverenga kuverenga. kuverenga etc.

Kuverengera kwekutungamira kwekutungamira ndiko kwehwaro hwechiziviso zviziviso zviziviso. Zvizhinji zveAlgorithms muCingerprint Chiziviso zvakavakirwa pane kutungamira, zvakadai sekutevera kwekupedzisira, kuongororwa kwemugunwe, node kuwirirana, etc. Yakawanda yea algorithms yakavakirwa pane zvekutarisa. Iyo nzira yekufambisa yekuverenga nzira yakavakirwa pane iyo grey chikamu pakati pePixels neyemapeji ine mhepo yekubvisa iyo pixel block Kuti uone kutungamira, iyo planti inoshandisa nzira yekubatira yekuverenga nzira yekuverenga Tora nhungamiro yakakwana sekutungamira kwemusha, uye kuverenga shanduko yeGraycle padhuze neimwe nzira, shanduko yeGireni padhuze, uye shanduko yeGraycle pamwe neiyo perpendicular kune zviyo zvikuru. Shandura mumapikisheni emagetsi emagetsi emagetsi emagetsi, fungisisa mafambiro emhando gumi nematanhatu. Saizi ye 32n32 block, uye uverenge kufungidzira kwega kwega mumativi akasiyana, tora nhungamiro nehukuru hwekutungamira kwekutungamira kwekugadzira, uye shandisa iyo Hierarchi yehukama network kuti uverenge munda wekuverenga. Parizvino, iyo inonyanya kushandiswa kufambisa nzira yekuverenga nzira inoenderana neGradient. Nzira yacho murombo. Iyi nzira inoverenga iyo Gradient Vector yemugunwe chifananidzo pane imwe yega pixel. Kutungamirirwa kweiyo Gradient Vector kunomhanya kushanduka kwechiitiko chemunwe wechigunwe padhuze nepixel, uye hukuru hweGradient Vector chinomhanya shanduko yekuchinja kweGraycale. Iyo pixel gradient pamucheto wechifananidzo mumufananidzo wakakura, gwara rekutungamira rakaverengerwa nenzira iyi yakatemwa neiyo pixels neiyo gradient, uye grandi reti yemucheto pamucheto wekunyora ndezvekunyorwa. kutungamira kwekutungamira. Kutungamira kwekutungamira kwenzvimbo imwe neimwe kunoenderana nemaguta ese ari munzvimbo iyoyo.
Iyo Gradient Vector ye pixel yakaverengerwa, uye iyo Gradient Vector nhungamiro yemucheto mufananidzo tambo kuruboshwe uye kurudyi mativi zvakangotarisana, kuitira kuti udzivise kudzima kwekuverenga. Mukuverenga, iyo antimony degree vector inoitwa, uye iyo yakaenzana Gradient Vector yemucheto pixels ichataura nenzira imwecheteyo Nekuti kutungamirirwa kweiyo yakaenzana gradient vector ndiyo yekaviri gradient vector, 1 ni yearavhareji kutungamira kweiyo yakanangana neyekwadi yeGradient vector nzira yekuvira. Dambudziko reGradient nzira nderekuti kana iyo apo iyo nzira yekukwevera yemapepa emucheto pixels haina kufanira kuti ive yako yekugadzira, iyo nzira isiriyo ichaverengerwa sechifananidzo chepakutanga, chinova nzira yekufungidzira. Kune akawanda fungidziro fungidziro yeiyo elliptical nharaunda, inokudzwa zvishoma nezvishoma yenzvimbo yemunharaunda yemunharaunda, kubva pakuswededza pamufananidzo wenyika, zvinogona kuoneka kuti mavheji emugumo emugumo pixels haasi perpendicular kune kutungamira kwekutanga, nokudaro zvichizoguma nenzira isiriyo nzira. Nzira yacho inogona kugadzirisa nzira isiriyo yebasa iri rega, asi kana nzira isiriyo mune imwe nharaunda izhinji, kwete chete pfungwa yekuraira isiriyo inogona kurangwa. Nhungamiro yakarurama icharuramiswa zvisizvo, uye kutungamirirwa pedyo nepfungwa yepakati kunowanzo kutsauka kubva kunzira yechokwadi mushure mekuderera-kusefa. Kana iyo curvature yeiyo gadziriro iri padyo nepfungwa yepakati yakakura.
