摘要： A Bayesian competitive model integrated with a generative classifier for unspecific person verification is described. In one aspect, a competitive measure for verification of an unspecific person is calculated using a discriminative classifier. The discriminative classifier is based on a Bayesian competitive model that is adaptable to unknown new classes. The Bayesian competitive model is integrated with a generative verification in view of a set of confidence criteria to make a decision regarding verification of the unspecific person.

摘要： The handling of occlusions in stereo imaging is disclosed. In one implementation, an association between a discontinuity in one stereo image and an occlusion in a second stereo image is utilized. In such an implementation, the first and second stereo images are segmented. A mapping of a discontinuity within the second stereo image is used to form at least part of a boundary of an occlusion in the first stereo image. The mapped discontinuity is found at a boundary between two segments in the second stereo image, and once mapped, divides a segment in the first stereo image into two patches. An energy calculation is made in an iterative manner, alternating with changes to a solution with the disparities and occlusions of the patches. Upon minimization, disparities and occlusions at the patch and pixel level are available.

摘要： Systems and methods of segmenting images are disclosed herein. The similarity of images in a set of images is compared. A group of images is selected from the set of images. The images in the group of images are selected based on compared similarities among the images. An informative image is selected from the group of images. User-defined semantic information of the informative image is received. The group of images as a graph is modeled as a graph. Each image in the group of images denotes a node in the graph. Edges of the graph denote a foreground relationship between images or a background relationship between images. One or more images in the group of images are automatically segmented by propagating the semantic information of the informative image to images in the group of images having a corresponding graph node that is related to a graph node corresponding to the informative image. Segmentation results can be refined according to user provided image semantics.

摘要： Progressive cut interactive object segmentation is described. In one implementation, a system analyzes strokes input by the user during iterative image segmentation in order to model the user's intention for refining segmentation. In the user intention model, the color of each stroke indicates the user's expectation of pixel label change to foreground or background, the location of the stroke indicates the user's region of interest, and the position of the stroke relative to a previous segmentation boundary indicates a segmentation error that the user intends to refine. Overexpansion of pixel label change is controlled by penalizing change outside the user's region of interest while overshrinkage is controlled by modeling the image as an eroded graph. In each iteration, energy consisting of a color term, a contrast term, and a user intention term is minimized to obtain a segmentation map.
摘要翻译：描述了渐进切割交互式对象分割。在一个实现中，系统分析用户在迭代图像分割期间输入的笔画，以便模拟用户的细化细分意图。在用户意图模型中，每个笔画的颜色表示用户对于前景或背景的像素标签变化的期望，笔画的位置指示用户感兴趣的区域，并且笔画相对于先前分割边界的位置指示用户打算细化的分段错误。像素标签变化的过度扩展是通过对用户感兴趣区域之外的变化进行惩罚来控制的，而通过将图像建模为受侵蚀图来控制超损耗。在每次迭代中，将由颜色项，对比度项和用户意图项组成的能量最小化以获得分割图。

摘要： Directed graph embedding is described. In one implementation, a system explores the link structure of a directed graph and embeds the vertices of the directed graph into a vector space while preserving affinities that are present among vertices of the directed graph. Such an embedded vector space facilitates general data analysis of the information in the directed graph. Optimal embedding can be achieved by measuring local affinities among vertices via transition probabilities between the vertices, based on a stationary distribution of Markov random walks through the directed graph. For classifying linked web pages represented by a directed graph, the system can train a support vector machine (SVM) classifier, which can operate in a user-selectable number of dimensions.
