median filter and k-means for dense disparity map estimation MATLAB functions to fill a sparse disparity map, in consequence, creating a dense disparity map. DEMO.m contains three examples with Tsukuba, Middlebury, and KITTI stereo datasets.

As input, the sparse disparity map must have NaN labels for occluded values, the reference RGB image and a minimum window size to perform the filtering. First the RGB reference image is color segmented from CIELab colorspace' 'a' and 'b' channels, then the median filtering stage is performed iteratively, beginning with a minimum window size, and then increasing its dimensions until there isn't NaN values or there isn't a value change between iterations

MEX functions were done with Armadillo linear algebra library, libgomp.dll is required to perform parallel processing
