Reinforcement Learning of Self Enhancing Camera Image and Signal Processing

1 code implementation15 Nov 2021 Chandrajit Bajaj, Yi Wang, Yunhao Yang

Our \textit{Recursive Self Enhancement Reinforcement Learning}(RSE-RL) model views the identification and correction of artifacts as a recursive self-learning and self-improvement exercise and consists of two major sub-modules: (i) The latent feature sub-space clustering/grouping obtained through variational auto-encoders enabling rapid identification of the correspondence and discrepancy between noisy and clean image patches.
