Multiresolution rotation invariant simultaneous auto regressive model for texture analysis

Two models, called the multivariate rotation-invariant SAR (RISAR) model and the multiresolution SAR/RISAR (MRSAR/MRRISAR) model, are presented. The information used by the in MRSAR/MRRISAR model is more complete and more independent. Many experiments on image classification using RISAR model and MRRISAR model indicate that these models have very strong classification power, wide area in which they can be used, very good rotation invariance, and high speed for recognition
