Target Detection in Hyperspectral Image Using Two Steps Reconstruction Based on Sparse Representation
摘要
Abstract
Aiming at the efficiency problem of traditional reconstruction algorithm for target detection in hyperspectral image, a two steps reconstruction algorithm was proposed. K nearest atoms with text pixel were calculated for representing the text pixel to calculate sparse vectors. This method solves the problem by calculating inverse matrix instead of iteration, which simplifies the process. The specific process of the method is given and the method is compared with the traditional and improved ones. Experimental results show that this method can improve the computation speed without decreasing the accuracy of detection.关键词
