A Wavelet based Lossless Video Compression using Adaptive Prediction and Motion Approximation

There have been great interests in developing efficient video compression techniques due to the increased multimedia applications in today’s era of digital technology. In this paper, we present a technique for lossless video sequence compression using predictive coding as a method to improve the compression efficiency. The proposed algorithm is an adaptive method that switches between predictio...

Encoding of Predictive Error Frames in Rate Scalable Video Codecs Using Wavelet Shrinkage

Rate scalable video compression is appealing for low bit rate applications, such as video telephony and wireless communication, where bandwidth available to an application cannot be guaranteed. In this paper, we investigate a set of strategies to increase the performance of SAMCoW, a rate scalable encoder [1, 2]. These techniques are based on based on wavelet decomposition, spatial orientation ...

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...

Evaluation of Wavelet Domain Block Motion Compensation (wbmc)

Wavelet based image compression has proved its superiority over DCT based methods. However, wavelet based techniques did not have so much success in video coding because motion compensation usually produces residuals that are not suitable for wavelet compression. This paper discusses a motion compensation technique which should fit naturally into wavelet based compression schemes. The motion co...

An enhancement to MRMC scheme in video compression

Zhang and Zafar proposed a video compression scheme based on the wavelet representation and multiresolution motion compensation (MRMC). In this letter, an additional masking module will be created to further enhance its efficiency. Specifically, between the modules of wavelet decomposition and MRMC, the masking module will be inserted which will construct binary images based on the difference o...
