Viewpoint missing in the train data

[Dávid Majerčák]

The train data annotations does contain only 3 classes for viewpoint (1, 2, 3), however, there are 4 classes described in the paper. I assume that the labels should be as follows:

• 1 - frontal
• 2 - side
• 3 - back
• 4 - no wear

If so, even though, there are some images with which are not wore by any person they still belong to one of the top 3 classes.

Code to reproduce the issue:

In README, it is defined as below:
viewpoint: a number, where 1 represents no wear, 2 represents frontal viewpoint and 3 represents side or back viewpoint.

@geyuying This means though that the plot in the paper cannot be reproduced using the data. What was the reason for abandoning the 4 class split?
