“…However, these traditional algorithms cannot accommodate the denoising requirements for 3DPIs because they perform the same denoising process for all channels. In recent years, in order to accommodate the denoising requirements for 3DPIs, algorithms have been developed using Robust Principal Component Analysis based algorithms, including Robust Principal Component Analysis (RPCA), Weighted Principal Component Analysis (WRPCA), and Cross-Channel Dynamic Weighting Principal Component Analysis (cc-DWRPCA) [ 13 , 27 , 28 ].…”
