Poisson2Sparse: Self-Supervised Poisson Denoising From a Single Image

1 code implementation4 Jun 2022 Calvin-Khang Ta, Abhishek Aich, Akash Gupta, Amit K. Roy-Chowdhury

In this work, we explore a sparsity and dictionary learning-based approach and present a novel self-supervised learning method for single-image denoising where the noise is approximated as a Poisson process, requiring no clean ground-truth data.

Ada-VSR: Adaptive Video Super-Resolution with Meta-Learning

no code implementations5 Aug 2021 Akash Gupta, Padmaja Jonnalagedda, Bir Bhanu, Amit K. Roy-Chowdhury

Specifically, meta-learning is employed to obtain adaptive parameters, using a large-scale external dataset, that can adapt quickly to the novel condition (degradation model) of the given test video during the internal learning task, thereby exploiting external and internal information of a video for super-resolution.
