Computing the Stereo Matching Cost with a Convolutional Neural Network [MC-CNN]

Running time:100 s
Environment:Nvidia GTX Titan (CUDA, Lua/Torch7)

Method Description:
We train a convolutional neural network to predict
how well two image patches match and use it to
compute the stereo matching cost. The cost is
refined by cross-based cost aggregation and
semiglobal matching, followed by a left-right
consistency check to eliminate errors in the
occluded regions.
Parameters:
See paper.

Detailed Results

This page provides detailed results for the method(s) selected. For each of the first 20 test images, the number of erroneous pixels at all thresholds is depicted in the table. Underneath, the left input image, the disparity / end-point error map and the estimated (and interpolated) disparity / optical flow map are shown. The error map scales linearly between 0 (black) and >=5 (white) pixels error. Red denotes all occluded pixels, falling outside the image boundaries. The false color map is scaled to the largest ground truth disparity / flow value.
