We propose a novel data embedding scheme for H.263 video coding. The proposed method, which can protect important information such as picture header and motion vector, is specific...
Applications such as traffic surveillance require a real-time and accurate method for object tracking. We propose to represent scene observations with parabola segments with an alg...

—In this paper, a new error concealment algorithm by recursive motion vector refinement is proposed. The proposed method utilizes the top/bottom motion vectors of lost MB in curr...
In this paper, a fast motion estimation algorithm for variable block-size by using a motion vector merging procedure is proposed for H.264. The motion vectors of adjacent small bl...
We propose a quad-tree scheme for obtaining sub-pixel estimates of interframe motion in the frequency domain. Our scheme is based on phase correlation and uses motion compensated ...
—A method for detection of tree branches and leaves in video is proposed. It is observed that the motion vectors of tree branches and leaves exhibit random motion. On the other h...
Among the various types of semantic concepts modeled, events pose the greatest challenge in terms of computational power needed to represent the event and accuracy that can be ach...
