摘要： 提出了一种以Walsh变换系数作为匹配基元的双目立体匹配方法。通过Walsh正交变换核对图像，变换得到Walsh系数，图像的特征被嵌入到该系数中，费用函数采用了Walsh变换系数作为匹配基元，而不是采用传统的像素灰度值。该文给出了算法的费用函数、匹配过程中相关的数据和最后的视差图。试验结果表明，将Walsh 系数作为一种匹配基元的方法是可行和有效的。

Abstract:

This paper proposes a new binocular stereo matching approach based on Walsh transformation. This approach gets the Walsh coefficient through transform image by using Walsh orthogonal transform kernel, after the transformation, the coefficient embeds the characters of images, so the characters of image are represented in the form of Walsh coefficients. The provided algorithm in the paper uses the Walsh transform coefficient as match base to replace the pixel gray value. The result disparity, relevant data and figures are listed in the paper and the result indicates that this approach of using Walsh coefficients as match primitives is possible and valid.

Key words: Stereo matching, Walsh transform, Transform kernel, Coefficient, Disparity computation
