Dense depth map generation using a single camera with hybrid auto-focusing

This paper proposes a novel depth map generation method using a pair of stereo images obtained from a single sensor. The proposed method generates a dense depth map as follows: i) sampling of the stereo image pair using photodiodes equipped with the black mask, ii) feature extraction in low light and noisy environment, iii) matching of the stereo images using motion estimation, and iv) matting of the matched image. Because stereo images are obtained using only one sensor, this method can estimate the depth information without special devices.
