In this paper, an efficient lip contour extraction scheme is proposed. From a given video frame, first the mouth region is extracted by using pixel threshold based binary conversion and detection of largest object in that region. Analysing the variation of pixel intensity pattern of RGB and a weighted colour plane, intensity ratio based lip region detection is performed, which provides accurate estimate...
This paper describes an automatic lip reading system consisting of two main modules 1) a pre-processing module able to extract lip geometry information from the video sequence and 2) a classification module to identify the visual speech based on dynamic lip movements. The recognition performance of the proposed system has been assessed in the recognition of the English digits 0 to 9 as spoken by the...
This paper proposes a face occlusion verification method for an automated teller machine (ATM) application. The proposed method mainly consists of three steps. Firstly, a head and shoulder shape is detected by applying B-spline active contour to motion edges. This motion edge is generated by a kurtosis-based frame selection and distance transformation-based motion edge detection. Secondly, a face...
This paper presents a style transfer algorithm of caricature. Rather than transferring texture from one image to another globally, we introduce an interactive tool for local texture transfer of caricature. As the segmentation algorithm is not very satisfactory for complex case of human face and the caricature, we use a brush by which the user draws some strokes on the source and target images to indicate...
