We conjecture that texture can be characterized by the statistics of the wa
velet detail coefficients and therefore introduce two feature sets: 1) the
wavelet histogram signatures which capture all first order statistics using
a model based approach and 2) the wavelet co-occurrence signatures, which
reflect the coefficients' second-order statistics.
The introduced feature sets outperform the traditionally used energy, Best
performance is achieved by combining histogram and eo-occurrence signatures
.
