deblurgan-v2

Use Case and High-Level Description

DeblurGAN-v2 is a generative adversarial network (GAN) for single image motion deblurring. This model is based on a relativistic conditional GAN with a double-scale discriminator. For details about architecture of model, check out the paper. Model used MobileNet as backbone and was trained on GoPro, DVD, NFS datasets. For details about implementation of model, check out the DeblurGAN-v2: Deblurring (Orders-of-Magnitude) Faster and Better repository.
