Abstract

This article presents the implementation of methods to improve Graph cut segmentation during initialization by initialization contour. It deals with a modified iterative method for improving the segmentation of heterogeneous objects in the input images. The modifications bring less dependence on user-set constants of Graph cut segmentation and thereby simplify the user interaction. It also deals with a modification for establishing the value of t-links edges in the graph for Graph cut segmentation. These modifications are experimentally tested on the input images intended for segmentation.
