Interactive Image Segmentation with Graph-Cut in Python

WebGraph cut formalism is well suited for segmentationof images. In fact, it is completely appropriate for N-dimensional volumes. The nodes of the graph can representpixels (or voxels) and the edges can represent any neigh-borhood relationship between the pixels. A cut partitions Ap=Ap= “obj” (4)“bkg”. (5) Webmore recent formulations in terms of graph cuts (e.g., [14, 18]) and spectral methods (e.g., [16]). Graph-based image segmentation techniques generally represent the problem in terms of a graph G = (V;E) where each node vi 2 V corresponds to a pixel in the image, and the edges in E connect certain pairs of neighboring pixels.
