Matlab Code For Image Segmentation Graph Cut (PDF)

WebA graph-based method is mainly based on the concept of maximum flow/minimum cut between the source and sink nodes in the directed graphs to segment the objects in the image. Graph cut (GC) methods are effective in medical image segmentation due to their global energy advantages. WebFinally, the building segments with high probability were consolidated by a graph cut optimization based on modified superpixel segmentation. The experimental results showed that this algorithm could extract buildings efficiently with 94% completeness, and the 87% correctness indicating its potential for many practical applications. green township michigan tax
