【摘要】：為了解決現(xiàn)有人像皮膚美化技術(shù)中出現(xiàn)的細(xì)節(jié)模糊以及特征丟失問題,提出一種基于構(gòu)建多重特征蒙板的人像皮膚美化技術(shù).第一重蒙板為利用高反差保留和強(qiáng)光迭加構(gòu)建的面部顯著瑕疵特征蒙板,基于該蒙板可預(yù)先去除人像面部的顯著瑕疵;第二重蒙板為利用膚色檢測構(gòu)建的人像背景特征蒙板;第三重蒙板為利用Face++算法構(gòu)建的面部關(guān)鍵區(qū)域特征蒙板;第二、三重蒙板的結(jié)合使用可以解決人像的背景特征及面部關(guān)鍵區(qū)域特征由于后續(xù)濾波處理而變模糊的問題;第四重蒙板為利用高反差保留構(gòu)建的面部立體視覺控制蒙板,該蒙板可在之前的皮膚美化處理基礎(chǔ)上還原人像的面部立體視覺特征.實(shí)驗(yàn)結(jié)果表明,該技術(shù)使用較小的皮膚美化系數(shù)即可去除瑕疵,并能在皮膚美化系數(shù)較大的情況下保留人像關(guān)鍵區(qū)域以及立體細(xì)節(jié)等真實(shí)感信息特征,從而解決人像皮膚美化過程中細(xì)節(jié)清晰度與瑕疵去除程度無法兼得的矛盾,最終達(dá)到人像美化的目的.
[Abstract]:In order to solve the existing technology in skin beautification portrait details and fuzzy feature loss problem, put forward a kind of beautification technology to build multiple features like skin mask. Based on the first mask to face significant defect feature is constructed by high pass and high light superposition Mongolia plate, significant flaw of the mask can be pre removed based on the portrait face; for the use of double mask mask portrait background characteristics building skin detection; face mask third key regional features constructed by Face++ algorithm mask; with second, third mask use can solve the key features of regional background features and facial portraits due to subsequent filtering and fuzzy problems; fourth for stereo vision control facial mask keep using high contrast mask construction, the mask before the skin beautification processing based on the reduction of portrait of the face Department of stereo visual features. The experimental results show that this technique uses smaller coefficient to remove defective skin beautification, and can beautify the large coefficient of retention of key area and three-dimensional details of realistic portrait information characteristics in the skin, so as to solve the contradiction of skin beautification portrait cannot both details defect removal process, the final achieve the portrait beautification.
