in this paper, we propose a new algorithm for subtitle text detection, extraction and text inpainting in color images. The proposed algorithm includes three stages. In the first stage, we localize text blocks to extract subtitles. We then extract the text characters precisely and in the third stage, we use an inpainting algorithm to recover the original texture of the image. To localize text blocks,...
Lip contour extraction is very important issue in visual speech recognition systems (lip reading). To extract the lip contour, proper segmentation is needed. There are many approaches for image segmentation such as colour segmentation (histogram-based and clustering-based) that have been widely used in different areas. In this paper we use RGB colour space and fuzzy C-means clustering for lip segmentation...
