What is directory structure for images and masks with multiple class?

[tclavelle]

Need to determine how to organize images and masks for multiple classes.

For example, is it image/line/masks or image/masks/line?

Looking at the load_masks() function should help resolve the issue (e.g. protobuff text file ids class when loading masks?)

Looks like the important part is that the class labels for each mask instance are returned in a np.array() by the load_masks() function. Thus, as long as we can determine which class each mask belongs to it shouldn't matter the directory structure that the input data is stored in. Easiest choice may be to indicate class in each instance mask.
