Rendering Correspondences

[johnwlambert]

Hello Rahul, Thank you for contributing this dataset.

Question for you -- I am looking at scene 31, where I see the following lines

397, 67, 425.00,604.00,1.440,1.968
397, 166, 422.00,614.00,1.436,1.981
397, 135, 430.00,622.00,1.482,2.095
397, 152, 451.00,689.00,1.396,1.998

in patchinfo.txt. When I render these images, and plot the corresponding points, they do not seem to be associated with the same 3d point. I am ignoring occlusion of course, which would mean they could still be the same 3d point, but visually we can't easily know this. Am I reading in the data incorrectly? If so, how can I take into account the occlusion when associating pixels?

Another example in Scene 31 is

336, 67,306,480,1.563,2.026,
336,135,302,494,1.574,2.227,
336, 40,317,516,1.574,2.200,
336,152,315,550,1.573,2.783,
336, 46,305,599,1.550,1.999,
336,117,314,566,1.547,2.919,
336,207,315,639,1.578,2.713,

It doesn't seem possible that these 2d points could be associated the same 3d point:

Thanks very much, John

Hello John, The RGB images are not indexed according to the "patchinfo.txt", I am uploading a second set of grayscale images with the same resolution that are correctly indexed.

[rmitra]

Grayscale images are uploaded in the 'images_GRAY' folder.

Thanks @rmitra for the quick reply. Would you also be willing to provide the RGB images with the correct indexing? I'm hoping to use the dataset for a project, and I need the RGB imagery, not grayscale imagery.

@johnwlambert I have fixed the indexing of the RGB images except for scenes 71, 88, 95.
