- Abstract:
-
Addressing the existing problem of difficulty in realizing fast segmentation of large-scale images under strong noise interference, a fast robust kernel space graph fuzzy clustering segmentation algorithm is proposed. This algorithm first mapped the samples in European Space to the high dimensional feature space through the kernel function; subsequently, it constructed the linear weighted filtering image using the gray scale and spatial information of the pixel neighborhood in the image to be segmented and carried out the robust kernel space pattern fuzzy clustering on the image. The fast iterative expression of robust kernel space graph fuzzy clustering was obtained by introducing the two-dimensional histogram information corresponding to the mean value of the current clustering pixel and its neighboring pixels. Experimental test results of large size images interrupted by Gaussian and salt-and-pepper noise show that the segmentation, robustness, and real-time performance of the proposed segmentation algorithm have improved more significantly than those of the picture-based fuzzy clustering, and other fuzzy clustering segmentation algorithms.
