Ignore image regions with a mask

[alex-klimov]

Colmap allows to ignore regions of the image for a feature extraction by providing a mask:

Does HLoc support similar functionality? I need that to ignore dynamic object in otherwise static scene.

There is already a PR for it: #190 It is outdated and I do not plan to merge it but it is straightforward to add.

Thank you! I will take a look.

@skydes Could you expand on what you mean by "It is outdated"? Do you mean there is a better way of doing PR #190 , i.e. better masking approach? Any references would help.

It is outdated in the sense that extract_features has seen many changes on the main branch. You might want to load the masks in the dataloader for better performance.
