Region-Based Segmentation and Wiener Pilot-Based Novel Amoeba Denoising Scheme for CT Imaging

Figure 8

Comparison of sparse-view FBP reconstructed image with classical and proposed amoeba schemes, applied on clinically reconstructed CT image. (a) 2-degree angular sampling-based sparse-view FBP reconstruction. (b) Classical amoeba filtering-based image denoising of (a). (c) Proposed scheme with RBS amoeba denoising of (a) using Wiener pilot image.
