WebIn this paper, we develop a trilateral weighted sparse coding (TWSC) scheme for robust real-world image denoising. Specifically, we introduce three weight matrices into the data and regularisation terms of the sparse coding framework to characterise the statistics of realistic noise and image priors. WebMar 1, 2024 · A curve can only be approximated by a series of “squares”, therefore, the image cannot be represented in the most sparse and optimal way. ... WNNM and TWSC get better PSNR values, it is because WNNM is based on nonlocal self-similarity, and TSCW is based on trilateral weighted sparse coding.

WebA Trilateral Weighted Sparse Coding Scheme for Real-World Image Denoising . Most of existing image denoising methods assume the corrupted noise to be additive white Gaussian noise (AWGN). However, the realistic noise in real-world noisy images is much more complex than AWGN, and is hard to be modelled by simple analytical distributions. WebSummary Most existing denoising algorithms will become less effective when applied to non-stationary complex noise. In this paper, we propose to use a trilateral weighted sparse coding scheme within the block matching framework for complex noise attenuation. Two weight matrices are introduced into the data-fidelity term of the sparse coding model to …
