Question about paper
abeyang00 opened this issue · comments
What is dense correspondence field exactly? There seems to be no explanation about this in the paper. And when i read your code, it seems like disparity is regarded as correspondence field??
Thank you in advance
Yes. For each pixel we predict a single scalar value specifying the disparity (i.e. scaled inverse depth). The "ground truth" disparity would point to the corresponding pixel in the second stereo view.
@macaodha Does the 'dl' mean the disparity of the right image in the equation(3)? Because in the paper, you indicate that the reconstructed right image(~Ir) can be obtained from left image(Il) and the disparity image(dr). For the disparity smoothness loss, you weight this cost with an edge-aware term using the image gradients. It means that the origin image should be correspondent with the disparity image in the Eq.3. But, according to the Eq.3, the 'Il ' isn't correspondent with the 'dl'.
I would really appreciate it if you could answer my question.
