We approximate the k -label Markov random field optimization by a single binary (s - t ) graph cut. Each vertex in the original graph is replaced by only ceil (log 2 (k )) new vertices and the new edge weights are obtained via a novel least squares solution approximating the original data and label interaction penalties. The s - t cut produces a binary "Gray" encoding that is unambiguously decoded into any of the original k labels. We analyze the properties of the approximation and present quantitative and qualitative image segmentation results, one of the several computer vision applications of multi label-MRF optimization.
