解釋
鋒面-
Robust non - frontal face alignment with edge based texture
基於邊緣紋理驅動模型的貝葉斯人臉定位 -
This paper proposes a new algorithm, called edge - based texture driven shape model e - tdsm, for non - frontal face alignment task. first, the texture is defined as the un - warped edge image contained in the shape rectangle ; then, a bayesian network is constructed to describe the relationship between the shape and texture models ; finally, expectation - maximization approach is utilized to infer the optimal texture and position parameters from the observed shape and texture information
姿態的變化使得人臉形狀的分佈變得非常復雜，特別是側臉圖像，由於自遮擋的原因，採用單一的模型有時候很難表達人臉形狀的分佈同時，再加上光照的變化，一方面使得人臉輪廓容易和背景混淆，另一方面有可能會在人臉上形成偽邊界，使得輪廓線被錯誤地定位到這些偽邊界線上。
