Ricardo Ralha (Instituto de Telecomunicações)

Running time:0.254 s
Environment:Dual - Nvidia GTX Titan (CUDA)

Method Description:
Real-time stereo pipeline using a symmetry-based
dense stereo algorithm and post processing
techniques to fill the pixels in the occluded
regions.
Parameters:
- Number of scales of the log-Gabor filters
- Shape factor
- Scaling step
- Center frequency of the mother wavelet
- Aggregation window
- Left–right consistency threshold

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.
