Extracting Corresponding Point Based on Texture Synthesis for Nearly Flat Textureless Object Surface

Figure 10

Changes in vertical camera angle. First row, from left to right: the first image is the left image in each image pairs; images from second to the end are the right images in each image pairs. The second row from (a) to (c): the number of TOP, OP, TTP, and TP under vertical camera angle changes with SIFT, SURF, and Harris-affine detectors, respectively. The third row: (a) the proportion of number of corresponding points on the objects compared to the original image pairs. (b) The proportion of number of corresponding points on entire image pairs compared to the original image pairs. (c) The ratio between the number of points detected on the object and entire image pairs.
