Location features

Hi @ChenRocks , I see the location features for each region is a 7-dimensional vector, so could you please tell me the order of coordinates? Is it [x1, y1, x2, y2, w, h, w ∗ h] or [y1, x1, y2, x2, h, w, w ∗ h]?
Thank you!

The issue does not identify a file, test, or entry point; begin by locating the code or documentation that defines the seven-dimensional regional location feature. Done means confirming the coordinate order and documenting that convention where the feature is defined.
