WebGraph cuts • In grouping, a weighted graph is split into disjoint sets (groups) where by some measure the similarity within a group is high and that across the group is low. • A graph-cut is a grouping technique in which the degree of dissimilarity between these two groups is computed as the total weight of edges removed between these 2 pieces. Webapproximately minimum solution using Graph cuts. Min-Cut/Max ow algorithms for Graph cuts include both push-relabel methods as well as augmenting paths methods. Boykov …
Standard Graph cuts: optimize energy function over the segmentation (unknown S value). Iterated Graph cuts: First step optimizes over the color parameters using K-means. Second step performs the usual graph cuts algorithm. These 2 steps are repeated recursively until convergence. Dynamic graph cuts: See more As applied in the field of computer vision, graph cut optimization can be employed to efficiently solve a wide variety of low-level computer vision problems (early vision ), such as image smoothing, the stereo correspondence problem See more Notation • Image: $${\displaystyle x\in \{R,G,B\}^{N}}$$ • Output: Segmentation (also called opacity) $${\displaystyle S\in R^{N}}$$ (soft segmentation). For hard segmentation See more • http://pub.ist.ac.at/~vnk/software.html — An implementation of the maxflow algorithm described in "An Experimental Comparison of Min-Cut/Max-Flow Algorithms for Energy Minimization in Computer Vision" by Vladimir Kolmogorov • See more The theory of graph cuts used as an optimization method was first applied in computer vision in the seminal paper by Greig, Porteous and Seheult of Durham University.
