This is the C implementation of the color guided AR model presented in "Color-guided Depth Recovery from RGB-D Data Using an Adaptive Auto-regressive Model" in TIP 2014. The original author provided MATLAB source code can be downloaded here:http://cs.tju.edu.cn/faculty/likun/projects/depth_recovery/index.htm. Our implementation can produce the same results as theirs. The difference is that we implement the method with C language and sparse matrix which is much faster and can handle much larger depth maps.
How to use
run MexFile.m first to compile the cpp file, then run main.m to perform experiments.
