Rotation Invariant Texture Recognition Using a Steerable Pyramid

A rotation-invariant texture recognition system is presented. A steerable oriented pyramid is used to extract representative features for the input textures. The steerability of the filter set allows a shift to an invariant representation via a DFT-encoding step. Supervised classification follows. State-of-the-art recognition results are presented on a 30 texture database with a comparison across the performance of the K-nn, back-propagation and rule-based classifiers. In addition, high accuracy estimation of the input rotation angle is demonstrate
