WebThis class will provide the introduction to fundamental concepts in computer Vision. Topics in this class include camera pose estimation, 3D reconstruction, feature detectors and descriptors, object recognition using vocabulary tree, segmentation, stereo matching, graph cuts, belief propagation, and a brief introduction to deep neural networks. WebGrabCut. GrabCut is an image segmentation method based on graph cuts . Starting with a user-specified bounding box around the object to be segmented, the algorithm estimates the color distribution of the target object and that of the background using a Gaussian mixture model. This is used to construct a Markov random field over the pixel labels ...

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 … WebIn this paper we describe a new technique for general purpose interactive segmentation …

Webcut C, denoted jCj, equals the sum of its edge weights. The minimum cut problem is to nd the cut with smallest cost. There are numerous algorithms for this problem with low-order polynomial complexity [1]; in practice these methods run in near-linear time.
