1. A method for reducing noise in an image from an image capture device comprising: (a) receiving an image from an image capture device; (b) processing said image in a manner to reduce offset fixed pattern noise in said image; (c) processing said image in a manner to reduce gain fixed pattern noise in said image; (d) filtering said filtered image as a result of step (b) and step (c) using a remnant fixed pattern noise filter applied over a first sliding window to reduce remnant fixed pattern noise, wherein said remnant fixed pattern noise filter is characterized by including an impulse filter applied over a second sliding window, smaller than and within, said first sliding window.
