Introduction into the Novel Two Dimensional Discrete Orthogonal Transforms Based on Rotation Angles

Electronics and Electrical Engineering 2011
Peteris Misāns, Uldis Derums

A brief description of the novel two dimensional discrete orthogonal transform based on rotation angles is presented. A unified approach for the definition of novel classes of orthogonal transforms is developed. The fast algorithms for the presented transforms are given. Five different subclasses of transforms are provided. A comparison of the number of operations for the calculation of transforms is given. Some examples of sets of basis functions are presented. An initial version of a tool for image analysis and synthesis and generation of basis functions is developed.
