Image partitions are used to find corresponding points between a pair of stereo images. The stereo images are first expressed by feature lines, and then these lines are partitioned into blocks on the basis of proposed degree of adjacency. These blocks are used as the units of correspondence. In correspondence, a coarse-fine procedure is taken into consideration, and the size of blocks are controlled at each correspondence stage. Correspondence between blocks of two images is done by using fuzzy operations of block properties, such as number of lines, directions, length. Experiment results show the effectivenesss of our approach.
