Paper Abstract

We introduce two texture classification techniques applicable to images compressed using block DCT. The first technique is a parametric approach. It models a texture as a stationary Gaussian process and utilizes the diagonalizing property of DCT. The second one uses the concept of power spectrum in the DCT domain. The energy distribution is employed to discriminate different textures. Both techniques work on compressed data without decoding and are designed to be robust against quantization noise.
