Morphological operators for image and video compression

This paper deals with the use of some morphological tools for image and video coding. Mathematical morphology can be considered as a shape-oriented approach to signal processing, and some of its features make it very useful for compression. Rather than describing a coding algorithm, the purpose of this paper is to describe some morphological tools that have proved attractive for compression. Fo...

Residue Sampling for Image And Video Compression

The chrominance subsampling has been widely used for the image and video compression. However, this can cause color distortion and image quality degradation. We developed a new sampling method in which the residual image after intra or inter prediction is subsampled instead of the original image subsampling. Since the residual image contains fewer information than the original image does genera...

Two Novel Chaos-Based Algorithms for Image and Video Watermarking

In this paper we introduce two innovative image and video watermarking algorithms. The paper’s main emphasis is on the use of chaotic maps to boost the algorithms’ security and resistance against attacks. By encrypting the watermark information in a one dimensional chaotic map, we make the extraction of watermark for potential attackers very hard. In another approach, we select embedding po...
