| Abstract: | In order to solve the problem that classical spectrum clustering algorithm can not calculate effectively for the large sea images,an improved spectral clustering algorithm is proposed.The partition method is used to divide the original image into multiple sub-images,and the collected samples are employed to estimate global samples combining with the random sampling algorithm.Thus,the computational complexity is greatly reduced on the basis of guaranteeing segmentation accuracy,and high dimensional images ar... |
