Comparison of marginal and multispectral filtering. Comparison of the performance of NR-NLM, NR-NLML, NR-MS-NLM and NR-MS-NLML filters was performed on simulated T2W brain images. Noise-free, noisy and filtered images are displayed for two different TEs. For each TE, the windowing of gray levels was adjusted to compensate for signal loss. Absolute error (AE) maps are displayed for each filter and each TE. The windowing of gray levels was identical between different methods to ensure a direct comparison between different methods. The results clearly show the superior performance of the NR-MS-NLML filter.
