We propose a cross-trees structure to perform the non-local cost aggregation for dense stereo matching. The cross-trees structure consists of a horizontal-tree and a vertical-tree. Compared to other spanning trees, the significant superiority of the cross-trees is that the trees' constructions are efficient and independent on any local or global property. Moreover, the trees are exactly unique. By...
In this paper, an effective constraint is proposed to leverage the stereo matching in early vision literature. Firstly, some particular edges are extracted to compose the new smooth constraint by categorizing the color edges into different groups. Then the optimal support windows can be established based on the proposed constraint. Finally, the disparity map would be estimated by using match propagation...
We propose a novel method on stereo matching based on the Global Edge Constraint (GEC) and Graph Cuts. Firstly, the GEC composed of particular image edges is employed to generate the initial disparity maps. And then the reliable disparity maps consistent with the observed data are extracted to construct the data term of the energy function. Finally, we incorporate the GEC as a soft constraint into...
A new method based on the Discrete Cosine Transform (DCT) and the Otsu method for blur detection in image sequences is proposed in this paper. In the first step, the standard deviation (STD) and the DCT coefficients are utilized to detect blurred and homogeneous areas in each image. Then, the Otsu method is used to calculate an adaptive threshold in each segment of the image sequence. Our experiments...
An efficient approach to detect and localize dining plates in images and videos based on human vision is reported in this paper. Rapid processing is achieved by using random checkpoints on edges only, simulating the knowledge based target search in biological visual systems. A new grouping algorithm based on convexity is presented for a top-down segmentation of candidate objects. Our experiments demonstrate...
As a means of biometric identification, gait analysis has attracted much attention in both research and industry. Most methods focus on human posture identification, tracking and medicine treatment assistant. Few methods, however, investigate the relationship between the load carried by an individual and the characteristics of his/her gait. In this paper, we present a method to estimate the weight...
