Abstract :
Intensifier Charge Couple Device (ICCD) is widely used in ultraviolet (UV) detection to amplify weak UV signal so that we can extract the target. While we amplify weak signals, inevitably the noise will also amplify. In this paper, according to the different characteristic of UV detection image, a Partial Differential Equation of Adaptive Median Filter (AMF-PDE) algorithm is proposed to process the output image of ultraviolet ICCD camera. The results show that AMF-PDE is able to recover submerged signal and preserve details of UV detection image efficiently.
