One of the most challenging issues in color guided depth map restoration is the inconsistency between color edges in guidance color images and depth discontinuities on depth maps. This makes the restored depth map suffer from texture copy artifacts and blurring depth discontinuities. To handle this problem, most state-of-the-art methods design complex guidance weight based on guidance color images...
Weak boundary contrast, inhomogeneous background and overlapped intensity distributions of the object and background are main causes that may lead to failure of boundary detection for many traditional active contour methods. In this paper, we propose a region-based active contour model to address these problems in both local and global ways. A localized active contour framework is developed, in which...
We develop a new algorithm for SLAM that uses a PTZ-camera for visual observation of natural landmarks. A new divided JCBB algorithm is presented to quickly address the visual data association problem without bounding the number of image features. Additionally, the presented orientation correction method is employed to well address the difficult SLAM orientation problem. The presented algorithm can...
