Method Description:
In this work we therefore utilize an energy
functional which is based on Total Variation
regularization and a robust data term. We propose a
novel, fast and stable numerical scheme to find the
minimizer of this energy. Our approach combines a
fixed-point procedure derived from duality
principles combined with a fast thresholding step.
Parameters:
use_structure_texture = 1;
structure_texture_sigma = 1.0;
structure_texture_factor = 0.8;
lambda = 70.0;
theta = 0.25;
epsilon = 0.1;
maxits = 10;
max_pyramid_levels = 1000;
pyramid_factor = 0.5;
warps = 5;

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.
