With wide use of multimedia applications, there are quite different demands in display resolutions and access bandwidths. There are also more demands in transcoding. At the same time, with being presented of the new video coding standard H.264, there are more high demands in transcoding. We present a fast algorithm based direction in I frame downsizing in H.264. This algorithm can significantly speed...
An efficient algorithm for facial features extractions is proposed. The facial features we extracted are the edges of two eyes, nose and mouth. The algorithm is based on an improved Gabor wavelets edge detector to detect the face region and facial features regions. The experimental results show that the proposed method is robust against facial expression, illumination, and can be also effect if the...
