Abstract:

Stereoscopic images created from video images and their associated depth data partly contain artifacts due to misalignment between depth and video data. To solve this problem, we present an algorithm of registration of depth and video data based on edge detection. First we use edge detection method to get the edge of the video image and the depth image respectively. Then we set the edge of the video image as the baseline to register the edge of the depth image. Experimental results show that by using the proposed algorithm the spatial alignment of depth and video data can be improved, leading to an alleviation of the observed artifacts in stereoscopic images.
