Graph cuts in computer vision

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, image segmentation, object co-segmentation, and many other computer vision … 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. Allan Seheult and Bruce Porteous were … See more Graph cuts methods have become popular alternatives to the level set-based approaches for optimizing the location of a contour (see for an … 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 … 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 • Minimization is done using a standard minimum cut algorithm. • Due to the Max-flow min-cut theorem we can solve energy minimization by maximizing the flow over the network. The … See more WebMany tasks in computer vision involve assigning a label (such as disparity) to every pixel. A common constraint is that the labels should vary smoothly almost everywhere while preserving sharp discontinuities that may exist, e.g., at object boundaries. These tasks are naturally stated in terms of energy minimization. The authors consider a wide class of …

WebNormalized cuts and image segmentation. Abstract: We propose a novel approach for solving the perceptual grouping problem in vision. Rather than focusing on local features and their consistencies in the image data, our approach aims at extracting the global impression of an image. We treat image segmentation as a graph partitioning problem … WebIn this paper we describe a new technique for general purpose interactive segmentation of N-dimensional images. The user marks certain pixels as "object" or "background" to provide hard constraints for segmentation. Additional soft constraints incorporate both boundary and region information. Graph cuts are used to find the globally optimal segmentation of the …
