When looking at the training images in the dataset (downloaded from here), I can see that 5473 images have a prefix of "HELEN", 251 of "IBUG", 2975 of "LFPW", 771 of "AFW" and out of the 18186 images in the train set, only 8878 have no such prefix. The images with the prefix are obviously augmented somehow, and have many repetitions of warpings of the same image.

Is this on purpose? Can you please explain this? The prefixes are of course names of other datasets, does this mean they were taken from these datasets?

I have downloaded some of these datasets to check this and I can confirm that the images with a prefix have been taken from these datasets.

Check 1: HELEN dataset

This is the image name in the LaPa dataset:

In the HELEN dataset it has the same name without the prefix and the suffix for the warping number:

Check 2: AFW dataset

For the AFW dataset, I'd say they have cropped the faces from the images based on the AFW landmarks, instead of using the full images:

This is what the image looks like in the AFW dataset:
