There have been several studies that jointly use audio, lip intensity, and lip geometry
information for speaker identification and speech-reading applications. This paper proposes …

We present a new multimodal speaker/speech recognition system that integrates audio, lip
texture and lip motion modalities. Fusion of audio and face texture modalities has been …

Lip tracking has played a significant role in a lip reading system. In this paper, we present a
local region based approach to lip tracking, which consists of two phases:(i) lip contour …

This paper studies the effect of combining evidences from multiple modes of speech on the
recognition of different categories of sounds. Multimodal speech recognition systems are …

We present an automatic lip contour extraction and tracking method based on an improved
active contour model, which introduces a novel image gradient detection based on the …

We present a lip contour tracking algorithm using attractor-guided particle filtering. Usually it
is difficult to robustly track the lip contour because the lip contour is highly deformable and …

This paper describes a lip localization algorithm within a still image frame for subsequent
tracking and audiovisual speech recognition processing. A Gabor filter-based feature space …

Lip features are the most important facial features, which are being extensively used in
various computer vision applications. Most of these applications like computer lip reading …

Lip segmentation is the first step of any audio-visual speech reading system. The accuracy
of this segmentation has a major influence on the performances of the global system. But …

This study investigated the change in lip movement during speech according to aging. For
the study, 15 elderly women with an average of 69 years and 15 young women with an …
