Claim:
1. A method for performing efficient edge enhancement of a digital image representing data from an infrared sensor, wherein the method is performed by a processor operating in association with a memory storing a computer program and at least one look up table (LUT), the method comprising; receiving, by the processor, image data acquired with an infrared sensor, the image data comprising an imaging array of pixel values, P formatting for display, using a first signal processing path of the processor, individual pixel values of the imaging array to generate an array of display-formatted pixel values, Pd for individual pixels in the imaging array, determining, using a second signal processing path of the processor operating parallel to the first signal processing path, an average or median pixel value, Pave for individual pixels in the imaging array, retrieving an edge enhancement factor, α for individual display-formatted pixel values, multiplying each image display-formatted pixel value, Pd displaying an enhanced image based on the enhanced display-formatted array of pixel values, Pe
