重建误差信息在立体匹配中的应用
Application of image construction error information in stereo matching

摘要: 对重建图像的误差信息在立体匹配中的应用进行了探讨:采用Tchebichef离散正交矩对图像进行重建并获得重建误差图像,使用基于窗口的匹配方法计算图像视差,并对几组立体图像对进行了实验和分析.结果表明,虽然重建误差信息没有重建后的图像信息量大,但利用其进行匹配依然可以得到较好的匹配结果.

Abstract: A new stereo matching approach based on reconstruction error information was proposed.The method reconstructs images using the orthogonal property of Tchebichef discrete orthogonal moments in image coordinate space.The reconstruction error image is computed.Several stereo image pairs are used to compute the disparity images in error image space using stereo match approach based on correlation window.The result indicated that the stereo match approach based on error images is possible and valid though its matching result is not better than the result computed in image space or reconstruction image space.-
