Abstract

Generally, an acquired stereoscopic image pair needs to be pre-processed geometrically before 3D viewing, because the parallax and alignment of the pair is not optimal for binocular vision. A stereo image obtained without using a specialized stereo camera system can have several problems that disrupt comfortable 3D viewing, such as insufficient or excessive baseline lengths between the two images. We present a reconstruction technique for the stereo pair images that maximizes visual comfort. First, a disparity map is generated from the stereo image by multiple footprints stereo algorithm, and then a synthetic stereomate is created using the disparity map and a right image of the given stereo pair. At this time, we adjust the disparity map to create a more realistic 3D effect. Most of the frequency disparity is reassigned to zero and the maximum disparity is revised as a parallax comfortable for human eyes. The occlusion of the synthetic stereomate is corrected by an inpainting method. Through the experiments, we could obtain a registered stereoscopic image with an optimized parallax. To evaluate the proposed technique, our results were compared with the original stereo pairs by viewing the 3D stereo anaglyphs.
