Abstract

In the paper is presented one new method for multi-view object representation based on image decomposition with Inverse Difference Pyramid. The method permits to obtain a very efficient description of the multi-view images using one of them as a reference one. The decomposition has a relatively low computational complexity because it is based on orthogonal transforms (Walsh-Hadamard, DCT, etc.). The relations which exist between transform coefficients from the consecutive decomposition layers permit significant reduction of the coefficients needed for the high-quality object representation.
