In a motion estimation for a group of at least one image element in a frame of a video sequence, a global motion is determined between the frame and a reference frame. Uncovered groups present in an uncovered region of the frame are identified based on the determined global motion. The ...
Therefore, the initial unsupervised segmentation problem is transformed to a supervised one, which allows us to accurately extract region and boundary information. Then, the regions compete for the image pixels in order to segment the whole image taking into account both information sources. The ...
The CRSs are determined by a region boundary graph (RBG) which is defined as a graph whose nodes represent regions, and the edges represent boundaries: convex and concave. Since jump boundaries represent no physical contact in 3-D, they are represented as null edges. A CRS is defined as a...

Edge grouping combining boundary and region information. This paper introduces a new edge-grouping method to detect perceptually salient structures in noisy images. Specifically, we define a new grouping cost fun... JS Stahl,S Wang - 《IEEE Transactions on Image Processing》 被引量: 136发表: 200...
Second, boundaries between moving regions are identified, and finally, a fine segmentation is performed within boundary regions using edge and color information. Experimental results show that the proposed method can segment moving regions fairly accurately, with sensitivity of 85% or higher, and ...

Boundary division of topographic statistical map, which provides convenience to matching region selection and route planning, can be accomplished quickly when using image edge detection on it. This article firstly introduced the characteristics of edge detection operators; the grayscale image was ...
The centre prior based methods fail in detecting object that are near boundary or touching boundary. Itti's model [61] breaks the objects into different segments and may assign different saliency scores to different segments of the same object because it uses local cues. The other approach ...
