Video Compression USING a New Active Mesh Based Motion Compensation Algorithm in Wavelet Sub-Bands

In this paper, a new mesh based algorithm is applied for motion estimation and compensation in the wavelet domain. The first major contribution of this work is the introduction of a new active mesh based method for motion estimation and compensation. The proposed algorithm is based on the mesh energy minimization with novel sets of energy functions. The proposed energy functions have appropriat...

Highly scalable video compression using a lifting-based 3D wavelet transform with deformable mesh motion compensation

This paper continues the development of a new framework for the construction of motion compensated wavelet transforms for highly scalable video compression. The current authors recently proposed a motion adaptive wavelet transform based on motioncompensated lifting steps. This approach overcomes several limitations of existing methods. In particular, frame warping and block displacement methods...

Wavelet video compression using region based motion estimation and compensation

We present wavelet based video compression algorithms. The motion estimation and compensation, which is an essential part in the compression, is based on segment movements. The proposed based codec sequentially employs the following steps: We first divide each frame in the sequence into blocks resulted from the block matching algorithm. The, we appply Hough transform, in order to group it into ...

Lossless Compression of Video Using Motion Compensation

Affine schemes in Mesh-Based Video Motion Compensation

We evaluate performances of different implementations of affine transform in motion compensation architecture based on a hierarchical adaptive structured mesh. The architecture predicts the next video frame using the reference frame, mesh code and mesh node motion vectors. It achieves significant reduction in describing the mesh topology by coding the splitting in recursive triangulation of the...
