Stereoscopic Panorama

Abstract

Both of image panorama and video synopsis are vital topics in the field of video post-processing In this work we aim at generating a long strip of stereo panoramic view from stereoscopic video to provide synopsis with depth perception The problem comes from that how to preserve disparity well and rectify panorama without loss of boundary information Previous approach focus on the generation of panorama from usual 2D video in addition only crop unwanted region after stitching step Unlike previous work after careful handling on key frame selection and disparity preservation in warping process our system minimize distortion on the image plane and maintain sense of depth With an eye to achieving appealing results our algorithm consists of three steps First we select representative frame intelligently from stereoscopic video Take image quality into consideration blurry or shaking frame must be avoided and the regional coverage of key frame must be assured Second we stitch these key frames into a panorama which have irregular boundary Finally we perform disparity-aware image warping step on left and right panoramic images to restore depth perception of original video and generate rectangular stereo panorama Following series of experiments we conclude our work is practicable for generating visually plausible stereoscopic panorama result and demonstrates the effectiveness of our method
