The SNR was computed for the original dataset and the denoised versions. For the median filtering, the standard of three iterations were used. For TOMOBFLOW, several tests with different iterations (from 10 to 300) were performed in order to study the evolution with time and to identify the decrease in resolution at high number of cycles.
