Abstract
A system and method for reducing frame-to-frame variations at the pixel level during noise reduction includes determining the noise source and the magnitude of those sources in the system. Once the system noise is characterized a selection of filters can be tailored to target the noise present in the system. The large temporal spikes, or impulse responses, in pixel value are considered to be discrete photon events. The system identifies pixels that have recently received a photon, preserving what little signal is present, while also suppressing Gaussian dark noise. The system implements a multi-level temporal wavelet filter.
