Webelementary cuts C on G and labellings that are one within one α- expansion of f. And the cost of a cut C on G is C = E( fC ). Proof :-– The label f p C at the pixel p determines which of the t-links to p is in C. – Also, labels determine which n-link e {p,q} between neighboring pixels {p, q} є N such that f p = f q be severed. WebThe α-expansion algorithm [3] involves global moves based on binary graph cut and typ- ically converges to low energy solutions in a few sweeps over label space. 2.1.
