Skin Color Weighted Disparity Competition for Hand Segmentation from Stereo Camera
نویسندگان
چکیده
This paper focuses on realtime hand segmentation from stereo camera, where the simple thresholding operation with the dense disparity map is not appropriate since it is time consuming to compute the dense disparity map, and proposes a novel method of skin color weighted disparity competition. The basic idea is that the hand disparity will be apparently different from most of the background disparities, and thus the hand pixel can be validated by verifying whether it satisfies the disparity limit of the hand more than of the background. This is why we call our method disparity competition.

متن کاملA View Synthesis Using Disparity Image
Binocular cues are perceived by rendering proper viewpoint images obtained at slightly different view angles. Since the number of viewpoints of the multiview video is limited, 3D display devices should generate arbitrary viewpoint images using available adjacent view images. In this project, we will use the disparity image to create new views of a specific subject starting from two pictures tak...
متن کاملSegmentation of lines and arcs and its application for depth recovery
In this paper we describe an advaced segmentation approach for stereo images improving the computation of depth compared to the commonly used straight line segmentation. Using a straight line – circular arc approximation of chain coded lines, the number of primitives is reduced significantly. This approximation lowers the computational effort as well as the frequency of erroneous matches. Start...
