In multiview video, illumination changes can occur due to imperfect camera calibration and variations of the camera position and direction. These characteristics can cause performance degradation in multiview video coding (MVC) that uses inter-view prediction by referring to the pictures obtained from the neighboring views. In order to overcome this problem, an adaptive local illumination change c...Show More
In this paper, we propose a heterogeneous transcoding method of converting an H.264 video bitstream into an MPEG-4 video bitstream. The proposed method reduces the spatial resolution for mobile terminals which support only low resolution video bitstreams. When the H.264 video bitstream is transformed into the MPEG-4 video bitstream, the conversions between the H.264 block types and the MPEG-4 bloc...Show More
In this paper, we propose a heterogeneous transcoding method of converting an H.264 video bitstream into an MPEG-4 video bitstream. When the H.264 video bitstream is transformed into the MPEG-4 video bitstream, the conversions between the H.264 block types and the MPEG-4 block types are performed by minimizing the distortion, and 4times4 block-based motion vector mapping is performed. The proposed...Show More
