An Efficient FPGA Implementation of Optimized Anisotropic Diffusion Filtering of Images

Figure 15

Results showing the original image, its noisy counterpart, and the denoised image and its various magnified portions of various sections of the denoised image of human skeleton. Image size = 512 × 512; the filter settings are as follows: Sigma () for random noise = 12, number of iterations = 4, in (3) = 1/7, and Kappa () in (4) = 15. (a), (b), and (c) show the zoomed insets of the scapula-humerus joint, true rib region, and the clavicle bone, respectively.
