Nonuniform Compression in Databases with Haar Wavelet
Data synopsis is a lossy compressed representation of data stored into databases that helps the query optimizer to speed up the query process, e.g. time to retrieve the data from ...

On Compression of Encrypted Video
We consider video sequences that have been encrypted uncompressed. Since encryption masks the source, traditional data compression algorithms are rendered ineffective. However, it...

Coding Artifact Reduction using Non-Reference Block Grid Visibility Measure
In this work a new method is proposed for coding artifact reduction of MPEG compressed video sequences. The method makes use of a simple cost-effective technique that allows the b...

An Efficient Real Time Low Bit Rate Video Codec
The implementation of a codec for real time applications such as video-conferencing at low bit rates is discussed. The discrete cosine transform has been used for compression, both...

Image super-resolution as sparse representation of raw image patches
This paper addresses the problem of generating a superresolution (SR) image from a single low-resolution input image. We approach this problem from the perspective of compressed s...
