In this report, two multiscale analysis based texture classification methods will be present and discussed. The first is to perform texture classification by modeling the dependence of shearlet subbands. Moreover, this method can also be used for texture retrieval when using a pseudo-feedback mechanism. The second method is to construct a Nonnegative Multiresolution Representation of image textures for classification. In this method, a Heterogeneous and Incrementally Generated Histogram (HIGH) and a Hessian regularized discriminative nonnegative matrix factorization are proposed to compute a compact representation of image textures. 报告人介绍： Yongsheng Dong（董永生）received his Ph.
