  Abstract

In this paper, as one of the disparity estimation algorithms for stereoscopic image, block-based Adaptive Field Dependent Search (AFDS) algorithm is proposed to be able to reduce encoding time and increase the quality of image at the same time. AFDS algorithm is a fast disparity estimate algorithm by used directional similarity of disparity vector and high spatial correlation between casual neighbor blocks on epipolar line. Performance of disparity estimator was improved by adapt a dynamic search range, To decrease disparity compensation error that is happened closed object at camera in stereoscopic images. As a result of simulation, computational load was decreased maximum 78% as a characteristic of image and PSNR was improved about 0.2-2.8 dB compared with former Block Matching Algorithm.
