Efficient Large-Scale Stereo Matching

This C++ library, which also includes MATLAB wrappers, can be used to transform a rectified stereo image pair into a disparity/depth map. By internally using the SSE instruction set and a prior over the disparity search space, it computes accurate depth maps of Megapixel input images in less than a second on a single CPU using recent hardware.

A demo file is included which shows the usage of the library with some Middlebury and Urban scene test images. If you want to use this library on your own data, please keep in mind that a good camera setup (shutter/gain), accurate calibration and adequate rectification is crucial for obtaining satisfactory results.
