Abstract

In this paper, we present a new stereo matching method with deformable windows to measure depth information more precisely. In order to correct the projective distortion between the left and right images, a window on the left image was deformed more than one window called deformable windows with a linear interpolation, and each deformable window keeps same texture pattern with different size. Stereo matching are performed simply by computing the normalized sum of squared difference (SSD) between the left and right images with deformable windows. The correspondence is determined by evaluating the matching score with a minimum of normalized SSD. The algorithm has been tested with real stereo image, and applied to measure the 3D-shape of human face. The results demonstrate the effectiveness of the stereo matching method with deformable windows.
