Comparison of low computational complexity filters suitable for real-time fluoroscopy image denoising

Abstract

Fluoroscopy devices provide real-time, radiographic movies of patient and it is widely utilized as support for surgery and in diagnostic. Low X-ray dose results in intense quantum noise, which is modeled as Poisson-distributed stochastic signal. Recently, a specific filter technique was introduced to suppress quantum noise in fluoroscopy. Filter operation… (More)
