Patent number: 10621722Abstract: The present invention disclosed an iterative analyzing method, which can detect the lesion in the image quickly. In brief, the iterative analysis method of the medical image disclosed by the present invention is roughly as follows: first, the original spectral image cube is expanded into a spectral image cube by a method of nonlinear dimensional-expansion, and then detecting the target's subpixel by the method of constrained energy minimization to produce an abundance image; the abundance image is fed back to the spectral image cube for create another spectral image cube by the nonlinear method. Furthermore, the abundance image is only used for detecting the subpixel of the target and does not include any spatial information, so, in order to obtain the spatial information of spectral image, it obtains the spatial information around the subpixel by using a blurring tool such as a Gaussian filter.Type: GrantFiled: July 10, 2018Date of Patent: April 14, 2020Assignee: TAICHUNG VETERANS GENERAL HOSPITALInventors: Chein-I Chang, Chi-Chang Clayton Chen, Jyh Wen Chai, Hsian-Min Chen
