Abstract
Official abstract text for this publication.
A method of generating an image enhancement function for enhancing an input image comprising a plurality of pixels to form an enhanced output image. The method includes receiving a reference image comprising a plurality of pixels; receiving an enhanced image derived from the reference image comprising a corresponding plurality of pixels; calculating a plurality of lookup tables, each of which maps a first plurality of pixel values to a second plurality of pixel values; and generating the image enhancement function comprising a spatially varying function of the lookup tables which when applied to the reference image generates an approximation to the enhanced image.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of generating an image enhancement function for enhancing an input image comprising a plurality of pixels to form an enhanced output image comprising a plurality of pixels, the method comprising: receiving a reference image comprising a plurality of pixels; receiving an enhanced image comprising a corresponding plurality of pixels, wherein the enhanced image is derived from the reference image; calculating a plurality of lookup tables, whe…
