From: Toward a priori noise characterization for real-time edge-aware denoising in fluoroscopic devices
Synthetic sequences with moving objects adopted to test the effect of the noise estimation errors on NVCA filtering performances. In the first row, panels a, b, the noisy sequences are reported, in which the contrast was set in order to obtain a CNR = 4. In the last row, panels c, d, the sequences denoised via the NVCA algorithm by using the actual noise parameters are shown
