keypoints out off the crop

Hi @michalfaber

keras_Realtime_Multi-Person_Pose_Estimation/training/augmentors.py

Lines 207 to 210 in b595cfb

	coords[:, 0] -= left_up[0]
	coords[:, 1] -= left_up[1]
	return coords

Here I think that you have to check if the keypoints are inside or outside the crop. I see that you checked the negative coordinates inside the point8_to_joints() functions but for the positive values that greater than (368, 368), I don't see any filter!

Hi @deeperdeeper
Thanks for the comment. There is no filtering in CropAug because its only purpose is to transform images and coordinates. I agree that there should be more strict filtering in point8_to_joints but the current implementation still gives the correct results. If a joint is outside of the area it will not be used to put a gaussian peak in the heatmap.

Thanks, @michalfaber, It is what I expected.
