Description
| - Článek se zabývá problémem sledování 3D tvaru rtů z 2D obrazu. Procej je zaměřen na sledování rtů v audiovizuálních nahrávkách z korpusu Czech in-vehicle audio-visual speech corpus (CIVAVC). Ve skutčném prostředí automobilu se hlava pohybuje v 3D prostoru. Změna orientace rtů v 3D prostoru zhoršuje výsledky rozpoznávání řeči. Proto jsme vytvořili algoritmus, který využívá 3D model rtů pro sledování jejich tvaru a 3D prostoru. (cs)
- In this paper, we present a solution to the problem of tracking 3D information about the shape of lips from 2D picture of a speaker. We focus on lip-tracking of audio-visual speech recordings from the Czech in-vehicle audio-visual speech corpus (CIVAVC). The corpus consists of 4 h 40 min records of audiovisual speech of driver recorded in a car during driving in an usual traffic. In real conditions a head of a speaker (a car driver) can move and turn in various directions. To cope with this movements and to avoid recognition errors caused by changing 3D position of lips, our algorithm utilizes a 3Dmodel- based approach to the lip-tracking process.
