The depth information is a fundamental factor in stereo imaging. The depth information of an object can be associated to the horizontal shift (with respect to the location in the parallax image) in a simple linear relation. Therefore, we can generate a stereo video by combining a regular monoscopic video with an artificial parallax video implemented with a designed horizontal shift. In this research, the manmade
horizontal shift is designed according to the pixel translations of the monoscopic
video obtained by the optical flow computation algorithm.
Optical flow proposed by Horn and Schunck was originally developed in the field of computer vision for the application of moving detection. Following this flow computation algorithm, a vector segmentation algorithm is applied to the flow field for grouping effects associated to the foreground. Finally, some merging procedures are applied to get a better foreground mask. With this foreground mask,the parallax video is then generated for creating our artificial stereo video.
