Applicability analysis of geometric linear transformations for video sequences compression

Przemysław Skurowski

Abstract


Standard video compression algorithms are based on motion vector prediction of images. There is potential possibility for enhancement of such an approach and creating an algorithm that predict images using motion vector rotation angle and scale factor as well. As a tool for searching these parameters and block matching there were Mellin and Fourier-Mellin transform proposed. The usability of proposed solution and the convergence of searching was verified against test images.

Keywords
