Claim 8:
9. The method according to claim 1, wherein a weight of a first edge of a superpixel node meets a formula of:

eij=G(|gi−gj|)+lij 

where i represents a superpixel node i, j represents another superpixel node j connected to the superpixel node i, eij represents a weight of a first edge connected between the superpixel nodes i and j, G(x) represents a Gaussian function, lij represents a length of a common edge between superpixel sets corresponding to the superpixel nodes i and j, gi represents a grayscale of the superpixel node i, and gj represents a grayscale of the superpixel node j.
