In this paper we focus on a novel issue in the field of video retrieval stemming from film analysis, namely the investigation of film montage patterns. For this purpose it is first necessary to reconstruct the origina...

To date, automatic recognition of semantic information such as salient objects and mid-level concepts from images is a challenging task. Since real-world objects tend to exist in a context within their environment, th...

A region-based variational model for color image segmentation is proposed using the chromaticity-brightness decomposition. By this decomposition, we extend the Wasserstein distance based method to color images. the ch...

A novel slice-layer double-step rate control (SLDSRC) scheme for H.264 is proposed. It not only resolves the problem of inter-dependency between rate-distortion (R-D) optimization (RDO) and rate control (RC), but also...
