Hello,
Thank you very much for releasing the dataset with images and poses. This is very useful to evaluate feature matching.
It seems that for the folders scene[6-8], the image extension switched to '.png' as opposed to '.jpg' for scene[1-7].
On Linux, it prevents the display of images using the 'Image Viewer' when scrolling over the images.
An easy fix is to simply rename the images with a 'jpg' extension.
Best,
Assia
