The difference is that none of the above examples actually process real image input - the Cartucho app utilizes stereo cam images.

I dont think so. It generates stereo images from 3D (not takes them as an input) so it is exactly related to blenderproc and other tools.

Yes... you are correct. My mistake.

Thank you for your work! Looking forward to the presentation. I had to look up MICCAI. To others: 23rd INTERNATIONAL CONFERENCE ON MEDICAL IMAGE COMPUTING & COMPUTER ASSISTED INTERVENTION (4-8 OCTOBER 2020) https://www.miccai2020.org/en

done! added to the GitHub README [presentation video]( https://imperialcollegelondon.box.com/s/cg54pddsf2pkx4ngf4pg... )

Love it! Should maybe add a link in addition to the video "image". Was not intuitive if it is a an image from a video or a link to a video (I am not used to video "preview" on Github).

Thank you! Yeah, I found that "hack" of the "image-video" in StackOverflow. Will add the link too as suggested

"synthetic ground truth"... isn't that an oxymoron?

Ground truth in this case means images with labels of some sort on parts of the image or objects in the image, not that they're real images themselves. So a cat in a photo with a label or mask on the cat would be "ground truth" on what part of the image a cat is in, or that there is a cat.

But if it's CG cat then it's not a real cat, hence not "ground truth".

Haha, just pointing out how the term is used in the industry. If you want to really play with semantics then I would argue that even a photo of a real cat isn’t a real cat and thus not ground truth. But while the consequences of that might have the awesome effect of clearing the shelters, it’s not practical, so we just call any labeled pixels representing a cat to a fidelity good enough for our purposes ground truth. ;)
