查询词典 occlusion

The combation of disparity consistency and matching cost are used to detect occlusion area. Fast and effective image segmentation is applied for extracting textureless and texture regions. The matching problem of textureless regions is then solved with constraint of disparity consistency and credibility concept. At the meantime, high credible seeds are obtained. Based on the smooth constraint of matching and disparity of seeds, dense disparity map is obtained via the adaptive-window based region growing.

然后采用视差一致性和匹配代价相结合的方法来检测遮挡区域；采用一种快速有效的图像分割算法提取了低纹理区和纹理区域，结合视差一致性和置信度约束来有效地解决低纹理区的匹配问题，同时得到一系列具有高置信度的种子点；根据立体匹配中的平滑性约束和种子点的视差，利用自适应窗口的区域增长技术最终得到致密的视差图。
