Method Description:
Computes a disparity map using the OpenCV block
matching algorithm, which is an implementation of Kurt Konolige's Small Vision System algorithm.
Parameters:
pre_filter_size 41
pre_filter_cap 31
sad_window_size 9
number_of_disparities 128
texture_threshold 20
uniqueness_ratio 10
speckleWindowSize 100
speckleRange 32

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.
