Nonlocal Coherent Denoising of RF Data for Ultrasound Elastography

Figure 3

Field II simulation results. The noisy input has substantially less contrast than the ground truth image. NLM is designed to remove speckle and therefore substantially reduces image detail. CODE output is closest to the ground truth. (a) Ground truth, (b) noisy, (c) NLM, (d) Gaussian on RF, and (e) CODE.
