WebHierarchical Sparse Coding We focus on the problem of extracting higher-level features of images by learning a second layer of sparse-coding bases on top of the first-layer activations. One desirable prop erty of high-level features is their invariance to small transformations, such as rotation or scaling. WebHierarchical Sparse Subspace Clustering (HESSC) HESSC is a Matlab toolbox, which includes a sparse-based clustering algorithm for hyperspectral image (HSI) analysis. This toolbox supports a journal paper accepted in Remote Sensing entitled "Hierarchical Sparse Subspace Clustering (HESSC): An Automatic Approach for Hyperspectral Image Analysis".
