• AMDCNet-architecture diagram.png: It shows the architecture overview of proposed AMDCNet. We perform three operations on the image: (a) Perform convolution template to get the visual sensitivity factor; (b) Calculate the initial cost of the image and construct the multi-directional aggregation template. (c) Detect left and right consistency to optimize.

In the sensitive points extraction stage, we propose a method to detects the edge points, contour points and other visual sensitive areas in the image, analyze the texture distribution difference between them and smooth areas, and guide the judgment weight of degree of freedom extension. In the multi-directional template matching stage, we first construct a multi-directional extension template, then, extended pixel length is guided according to the visual sensitivity, finally, we complete the whole image processing. In the optimization stage, we propose left and right consistency detection method to further reduce the error matching rate.

• Figure1.png: This figure shows the comparison of different test results. The first column is the perspective image in the original image of the experimental data set, the second column is the ideal parallax image for reference, the third and fourth columns are the result images obtained by the classical algorithm census, and the fifth and sixth columns are stereo matching algorithms based on visual sensitive information. Among them, the red marks in the fourth and sixth columns indicate the mismatching areas of the marks when comparing the two result maps with the ideal disparity map. Through the display of subjective images, we can clearly see that the proposed algorithm can effectively calculate and generate the disparity of the original image, and the matching effect is better than that of the classical algorithm.
