ビデオフレームからの顔部品-目および唇領域-の特定ならびにその抽出

摘要

近年，顔から得られるそれらの情報をコミュニケーションメディアやヒューマンインタフェースへ応用し，コンピュータに人間の顔を認識させる研究が盛んに行われている．例えば顔の個人性に注目し，コンピュータに特定の人物の顔同定をさせることでセキュリティに応用することが可能である．%In this paper the idendification of facial parts and their automatic extraction for the recognition of facial expression is presented. Before the recognition of facial expressions can be achieved, each facial parts, such as eyes, mouth, and so on, must be precisely extracted. The identification of facial parts, however, is very difficult in general even using color and movement information. In order to identify the mouth and eyes, Q-element in the YIQ color system and Qc-ele-ment in the modified HSV color model were used. The extraction of facial parts is executed based on template matching. The template used was devised so that the adequate position of the template can be easily identified.
