WebJun 1, 2024 · The performance of SDnDTI is systematically evaluated in terms of the quality of output images and DTI metrics, as well as compared to supervised learning based denoising and conventional state-of-the-art denoising algorithms BM4D, AONLM and MPPCA on two different datasets provided by HCP and HCP-A. SDnDTI-denoised … WebJan 1, 2015 · For the purpose of comparison, block-matching and 3D/4D denoising algorithm (BM3D/BM4D) were also adopted to denoise the projections. Experimental results demonstrated that the proposed algorithm could deliver a reconstruction with comparable quality as BM4D algorithm while better than that of BM3D denoising algorithm.
