Stereo matching cost volume visualization

MATLAB gui project: it visualizes the distribtuion of the cost volume of stereo matching.

Simply run main.m using MATLAB.

This project was designed to discover the problems of AcfNet. it visualize the binomial distribution problem in AcfNet.

it supports various visualization such as error, confidence map, etc. Note that the reliability of AcfNet is high in areas with large errors. through this project, i discovered a problem with AcfNet.
