Abstract
The gradient orientation pattern matching technique (GOPM) is a block matching technique based on gradient orientations. In this paper, we evaluate this method for stereo matching applications under various conditions that include irregular lighting, occlusion, image blurring, and noise. The performance of the GOPM is compared with that of the standard block matching technique with the sum-of-absolute differences (SAD) metric. Experimental results show the advantages and disadvantages of the GOPM.
