An efficient, local image-based approach for extraction of intransient facial features and
recognition of four facial expressions from 2D image sequences is presented. The algorithm …

In audio-visual speech recognition (AVSR), it is beneficial to use lip boundary information in
addition to texture-dependent features. In this paper, we propose an automatic lip …

The effective automatic lip extraction from images is fundamental in a variety of applications.
Since the outer labial contour of the mouth is very poor color distinction when compared …

Lip contour detection and tracking is the most important pre-requisite for computerized
speech reading. Several approaches have been proposed for lip tracking after lip contour is …

In this paper, a new algorithm for lip tracking is proposed, fusing the strength of stochastic
tracker and deterministic tracker. Particle filter and Active Shape Models (ASM) are used as …

We develop a PC-based quantitative asymmetry analyzing system for facial palsy patients.
To collect frequent data, the system is designed to maximize the chance of measure and …

We propose a method of image segmentation using a Gaussian mixture model of the colour
image histogram. The model construction is based on the model validation philosophy of …

This paper presents an algorithm to estimate the state of open or closed mouth in real time
video streaming. It detects associated frequency of mouth motion events in specific time …

In this technical paper, an ingenious approach explained and developed with respect to face
recognition and gender classification via Lip detection feature: a computer system which can …

Image segmentation is the first step in image analysis. The objective of image segmentation
is to divide an image into connected, homogeneous regions such that subsequent …
