Hi, was trying to use the repo and noticed your post. If you haven't already figured it out...

You were spot on with the first ones, but more specifically:
obj - Name of the specific image
img1-2 - We are matching the image with "view 1" onto the image with "view 2"
Him, Wim - Height and width

The Hxy field is a little bit more in-depth. The collection of these actually refers to a 2D matrix (3x3 in this case) called the "Homography Matrix" (H). The whole matrix tells us how we can project image with "view 1" onto image with "view 2" such that they are essentially overlayed. It is a whole CV topic (https://docs.opencv.org/master/d1/de0/tutorial_py_feature_homography.html).
