  Abstract

In this paper, a new intermediate view reconstruction method employing a stereo image rectification algorithm by which an uncalibrated input stereo image can be transformed into the calibrated one is suggested and it., performance is analyzed. In the proposed method, feature points are extracted from the stereo image pair through detection of the corners and similarities between each pixel of the stereo image. And then, using these detected feature points, the moving vectors between stereo image and the epipolar line is extracted. Finally, the input stereo image is rectified by matching the extracted epipolar line between the stereo image in the horizontal direction and intermediate views are reconstructed by using these rectified stereo images. From some experiments on synthesis of the intermediate views by using three kinds of stereo images; a CCETI's stereo image of 'Man' and two stereo images of 'Face' & 'Car' captured by real camera, it is analyzed that PSNRs of the intermediate views reconstructed from the calibrated images by using the proposed rectification algorithm are improved by 2.5dB for 'Man', 4.26dB for 'Face' and 3.85dB for 'Car' than those of the uncalibrated ones. This good experimental result suggests a possibility of practical application of the proposed stereo image rectification algorithm-based intermediate view reconstruction scheme to the uncalibrated stereo images.
