Why the Dist. to Target grows with the epoch?

[iDTer]

Epoch 28:
Loss = -0.5512599
Dist. to Image = 0.9096553
Dist. to Target = 0.3583954
Face detection = True
Epoch 29:
Loss = -0.5638140
Dist. to Image = 0.9396414
Dist. to Target = 0.3758273
Face detection = True
Epoch 30:
Loss = -0.5764654
Dist. to Image = 0.9016970
Dist. to Target = 0.3252316
Face detection = True

I feel like the end result is blending the perturbation on the original face image instead of masking it directly. And I found that as the epoch increases, the perturbations appear more and more sparse.

Yeah, this is an issue that results from RGB values being mapped between [0,1]. I think it's some issue regarding allowing an alpha to be applied to RGB values or something of that sort. I am not actively developing this so if you pin-point the specific problem, feel free to either comment here or make your own pull-request.

I am happy to bounce ideas back and forth with you too!
