Keywords: Image process, Dense corresponding pixel matching, Markov Random Field, Fixed Window, RGB independent Information Abstract. A fixed window based algorithm is proposed for dense corresponding pixel matching between epipolar images. The algorithm makes full use of three colour components, R, G and B, and simplifies determining the optimal window. In order to reduce the impact of obvious colour difference between corresponding pixels, the proposed algorithm uses more information from neighbouring pixels, and adjusts the contributions of the central pixels and their neighbouring pixels. Two pairs of epipolar images are tested using the fixed window based algorithm. The experimental results, including boundary testing, sampled corresponding pixels’ evaluation and 3D point cloud check, demonstrate the effectiveness of the proposed algorithm.
