LFW directories are non-standard
It appears that the directory structure for the LFW dataset is set to an idiap-specific location. By default, there is no relative path like this: https://gitlab.idiap.ch/bob/bob.bio.face/-/blob/ead8c069bafb4024dc15c5df7fdc878aec8bd5f0/bob/bio/face/database/lfw.py#L87
When downloading the images from the LFW web page, they get extracted into directories lfw
or lfw_funneled
(for the funneled version). In my eyes it would be more sensible to used these directories instead, i.e., use lfw
when no annotation directory is specified, and use lfw_funneled
when annotations are provided.
Another way would be to have two distinct entries for lfw-view2
, such as lfw-view2-aligned
(funneled images and annotations) and lfw-view2-raw
(original images, use detectors).
