GPU-Based Block-Wise Nonlocal Means Denoising for 3D Ultrasound Images
Figure 5
Denoised results of the ultrasound fetus: (a1)–(a3) the denoised result of the traditional NLM with the similarity window radius changing from 1 to 3; (b1)–(b3) the denoised result of the proposed NLM with the similarity window radius changing from 1 to 3.
