Spectral–spatial representation based algorithms have been widely applied in hyperspectral image (HSI) classification, which exploit the fact that pixels in a local patch often have similar spectral reflectance values and probably belong to the same class. Collaborative representation (CR) is a typical supervised classification method for high-dimensional data, which has been widely used for spectral–spatial...
In this paper, we proposed a new approach to solve the clustering problem in which the cluster number is uncertainty. It utilizes IWO (Invasive Weed Optimization) algorithm to optimize two fuzzy clustering objective function simultaneously, and a variable-length real-coded scheme has been adopted, the variable length weed encodes the cluster centers with variable numbers. In order to keep the diversity...
