附:论文摘要内容

Joint sparse representation based classifier assumes that pixels in a local window can be jointly and sparsely represented by a dictionary constructed by the training samples. The class label of each pixel can be decided according to the representation residual. However, once the local window of each pixel includes pixels from different classes, the performance of the JSR classifier may be seriously decreased. Since correlation coefficient (CC) is able to measure the spectral similarity among different pixels efficiently, this letter proposes a new classification method via fusing correlation coefficient and joint sparse representation (CCJSR), which attempts to use the within class similarity between training and test samples while decrease the between-class interference. First, the correlation coefficients among the training and test samples are calculated. Then, the sparse representation based classifier is used to obtain the representation residuals of different pixels. Finally, a regularization parameterλis introduced to achieve the balance between the JSR and the CC. Experimental results obtained on the Indian Pines data set demonstrate the competitive performance of the proposed approach with respect to other widely used classifiers。
