Method Description:
Unsupervised Stereo Matching methods have made
significant strides recently. However, these
approaches have predominantly relied on the
assumption of photometric consistency, leading to
potential limitations: sensitivity to illuminance
changes and difficulty in dealing with problematic
areas like occluded or textureless regions.
To mitigate these limitations, this paper
introduces a novel self-supervised dual-level
framework named \textbf{\textit{Dual-Net}}.
This framework mainly consists of two key
components: self-supervised teacher training and
student training based on knowledge distillation.
Specifically, the teacher model is first trained
in a self-supervised fashion with a focus on
feature space and data augmentation consistency.

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.
