摘　　要：视差估计在立体图像编码、视频检索、立体图像分割等领域有重要的应用,是进行图像、视频分析的基础。首先,基于模糊隶属度提出了一种基于差异的视差估计方法;其次,引入模糊隶属度,把图像灰度转换为差异值;然后,分析了多块匹配的优越性;提出了基于多块匹配的视差估计方法;最后,在Middlebury网站上的测试结果证明了该方法的有效性。Disparity estimation is a basic analytic method for images and video and is highly used in fields like stereo image cod- ing,video retrieval and stereo image segmentation. A new disparity estimation method based on the membership degree in fuzzy mathematics is proposed. In this paper, the membership degree is introduced, gray values of the image are transformed to difference values. Meanwhile ,the superiority of the multi-block matching is analyzed. The new method based on the idea of block matching constructs a muhi-block matching algorithm. The experimental results based on the Middlebury stereo datasets demonstrate that this method can achieve a better performance.
