Tsarin Algorithm na Affine da Tsarin SIMD don Matsa Bidiyo tare da Ƙananan Aikace-aikace
Wannan takarda ta gabatar da sabon algorithm na tushen affine da tsarin gine-ginen SIMD don matsawa bidiyo tare da ƙananan aikace-aikacen ƙimar kuɗi. Ana amfani da algorithm ɗin da aka tsara don ƙididdige motsi na tushen raga kuma ana kiran sa algorithm matching matching na tushen raga. (MB-SMA). MB-SMA shine sauƙaƙan siga na algorithm ɗin daidaitawa hexagonal [1]. A cikin wannan algorithm, Rana mai kusurwa uku-dama ana amfani da ita don fa'ida daga haɓakar algorithm kyauta wanda aka gabatar a ciki [2] don lissafta sigogin affin. Algorithm ɗin da aka tsara yana da ƙarancin ƙididdiga fiye da algorithm matching hexagonal yayin da yake samar da kusan mafi girman sigina-zuwa amo. (PSNR) dabi'u. MB-SMA ta ƙetare algorithms kimanta motsi da aka saba amfani da su dangane da ƙimar ƙididdigewa, inganci da ingancin bidiyo (i.e, PSNR). Ana aiwatar da MB-SMA ta amfani da tsarin gine-gine na SIMD wanda a ciki an saka ɗimbin abubuwan sarrafawa tare da tubalan SRAM don amfani da babban bandwidth ƙwaƙwalwar ajiya na ciki.. Tsarin gine-ginen da aka tsara yana buƙatar 26.9 ms don aiwatar da firam ɗin bidiyo na CIF ɗaya. Saboda haka, yana iya aiwatarwa 37 CIF Frames/s. An ƙirƙira tsarin gine-ginen da aka tsara ta amfani da Kamfanin Masana'antu na Taiwan Semiconductor (Farashin TSMC) 0.18-An ƙirƙira fasahar CMOS μm da SRAM ɗin da aka saka ta amfani da mai haɗa ƙwaƙwalwar ajiya na Virage Logic.
