A hybrid approach to mouth features detection
Maja Pantić, M. Tomc, Léon J. M. Rothkrantz · 2002
This paper presents a novel, robust and flexible method for extracting four mouth features (top of the upper lip, bottom of the lower lip, left and right mouth corners) from facial image sequences. While robustness is referred to subject variability, pose, and image quality, flexibility is begotten by efficient fusion of several information sources and expounding the certainty of the generated results.
