—Embedded zero-tree coding in wavelet domain has drawn a lot of attention to the image compression applications. Among noteworthy zero-tree algorithms is the SPIHT algorithm. For...
We study the compression problem of visual scenes acquired with a camera for transmission or storage. Our proposed model is general and includes two well-known cases: that of vide...
In this paper we combine model-based video synthesis with block-based motion-compensated prediction (MCP). Two frames are utilized far prediction where one frame is the previous d...
—In this paper, we present an original image quality metric for open-loop transcoding architectures based on frequency selective transmission. The proposed metric computes the no...
Digital images can be forged easily with today’s widely available image processing software. In this paper, we describe a passive approach to detect digital forgeries by checkin...
