As you can see above results, the samples of BEGAN has speckle artifacts. It can be reduced by adjusting gamma.

* The images become whity and cloudy as the learning progresses. I don't know if it is right to express, but it certainly does.

* This phenomenon has been seen in CycleGAN before. CycleGAN is based on LSGAN, but LSGAN does not have this whitening phenomenon.
