Tekinoloje yala ndi chala chala kuchokera ku chithunzi cha chala chala cham'manja m'gulu la zala zowongolera

Zida zala zomwe zimagwiritsidwa ntchito ndi makina owongolera zala zam'manja mu chizindikiritso cha chala ndi malo ndi mizere, ndi mfundo imodzi. Zojambula zobwezeretsanso zala zimagwiritsidwa ntchito popanga zala. Maukadaulo ofunikira omwe akukhudzidwa ndi zala zala ndi kuphatikiza kuwerengera kwa mapangidwe, kuwerengera pafupipafupi, kukhazikitsa zala ndi kusefukira kwala ndi kusefukira, ndi kusefa kwa mapangidwe. kuwerengera etc.

Kuwerengera kwa kapangidwe kake ndi maziko a chizindikiritso cha chala. Ambiri mwa algorithms mu chizindikiritso cha chala cham'manja amatengera malangizo, monga kuwerengera mobwerezabwereza, kutsata mapangidwe a Pargentine, Kupeza Zala Zam'mimba, Etc. Ambiri a Algorithms ndi okhazikika pa mayendedwe. Njira yowerengera yowerengera imakhazikitsidwa ndi imvi pakati pa ma pixels, imafanizira chinsinsi chilichonse cha 2x2 ndi ma template anayi a Pixel block, kenako ndikuyerekeza kuti ndizovuta kwambiri ngati ndizovuta Kuti mudziwe momwe akuwongolera, purneycale yolumikizira njira yolumikizira mapangidwe, akuwonetsa njira zogwirira ntchito, ndikuwerengetsa zisankho za Proyscale pa pixel iliyonse. Tengani malangizowo ndi njira yabwino kwambiri polowera kunyumba, ndikuwerengetsa kusintha kwa gayyscale kutsogolo kulikonse Sinthani pixels yolembedwa ndi ma pixel osanenedweratu, tsimikizani ma pixel ophatikizika, ndikuwerengetsa kusasinthika kwa pixel iliyonse mbali iliyonse ya pixel, ndikugawa chithunzi cha chala. Kukula kwa 32n3 Pakadali pano, njira yowerengera yogwiritsidwa ntchito kwambiri yogwiritsidwa ntchito kwambiri imakhazikika pa gradient. Njirayi siili wosauka. Njira iyi imawerengera mawonekedwe a chithunzi cha chala pa pixel iliyonse. Malangizo a vekitala a gradied amaimira kusintha kwa ma scayscale kwambiri pa chithunzi cha chala kudzera pa pixel, ndipo kukula kwa verctor verctor kumayimira liwiro la kusintha kwa stayyscale. Pixel Gradient m'mphepete mwa kapangidwe kake ndi wamkulu, malangizo omwewa amatsimikiziridwa ndi pixel ija yomwe ili ndi mawonekedwe okulirapo, ndipo njira yolumikizira chithunzicho ndi kapangidwe kake. Kuwongolera kwa dera lililonse kumadalira mizinda yonse m'derali.
Vecdwient of pixel imawerengeredwa, ndipo mawonekedwe a vectord a vector a chingwe chakumaso kumanzere ndi kumanja kwa mawonekedwe a kumanzere ndi kosiyana, kuti mupewe kuletsa kuchotsa. Pakuwerengera, cholembera cha antictic dixper chimawoneka, ndipo vekesed stradone verct wa ma pixel kumanzere ndi kumanja kwa mawonekedwe omwewo adzaloza mbali yomweyo, kenako chitsogozo cha squared chimawerengeredwa. Chifukwa choti njira ya squadle yolumikizira imathandizira kawirikawiri pa squed, 1 NI mwa chitsogozo chambiri cha squared verctor ndi njira yolunjika ya kapangidwe kake. Vuto lokhala ndi njira yodziwikiratu ndikuti pomwe njira yotsogola ya pixel ambiri sioyenera kuwongolera kapangidwe kake ka mawonekedwe, njira yolakwika idzawerengedwa ngati chithunzi choyambirira, chomwe chingachitike. Pali ziwonetsero zambiri zolakwika m'dera la elliptical, lomwe likukulitsa mwachidule chithunzi cham'deralo, kuyambira pomwe pali chithunzithunzi cha dziko lonse, chimatha kuwoneka kuti ma pix ambiri a ma pixel sakhala ocheperako kuwongolera kapangidwe kake, motero kumabweretsa chizolowezi cholakwika. Njira itha kukonza malangizo olakwika a ntchito yapafupi, koma njira yolakwika yomwe ili pamalo ena ndi ambiri, osati lingaliro lolakwika lokhalo lomwe lingayendetsedwe. Malangizo olondola adzakonzedweratu molakwika, ndipo njira yomwe ili pafupi ndi malo ozungulira nthawi zambiri imasiyanitsa kuchokera kumbali yeniyeni pambuyo posefa pang'ono. Pamene kutukuka kwa kapangidwe kake pafupi ndi koro ndikokulira.
