Tensorflow implementation of Collaborative GAN ( CVPR2019, ORAL).
The main codes have two parts: one is Collaborative Generative Adversarial Networks for facial expression imputation problem. The Collaborative GAN is a deep learning model for missing image data imputation (Dongwook Lee et al. CVPR 2019). The concept for the missing image imputation is applied for facial expression imputation problem and this is the implementation of that using tensorflow.
This repository provides a tensorflow implementation of CollaGAN for missing MR contrast imputation as described in the paper:
