- W2368807796 abstract "According to spectral graph theory,a new method of determining the cluster number of image is proposed for resolving the accuracy problem in this paper.The relationship between the number of zeros eigenvalue of Laplace matrix of weighted graph and the cluster number of image is studied.By analyzing the ideal format,block format and general format of Laplace matrix of weighted graph,we have deduced that the cluster number of image is closed to the number of zeros eigenvalue of Laplace matrix of weighted graph via the matrix theory.In the numerical simulations,the parameter of weighted graph is discussed and it shows that we can get the accurate cluster number of image when the parameter is limited to 0.4 and 0.6.Meanwhile,the numerical result employing our method is better than that of using the number of one eigenvalue of weighted matrix." @default.
