Method Description:
A novel two-branch deconvolutional network
(TBDN) is proposed to learn the shared weights
from
stereo image pairs, which can obtain the shared
weights of
each layer by training in greedily layer-by-layer
manner. We
present a feasible iterative algorithm to solve
the TBDN, and
analyze the corresponding convergence
mathematically and the
computational complexity. The shared weights
obtained by the
pre-training of the two-branch deconvolutional
network are used
as the initialization of the designed disparity
estimation network.
Finally, the weights of all layers in disparity
estimation network
are further fine-tuned using the backpropagation
method.
Parameters:
\beta_1= 0.9,\beta_2 = 0.999

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.
