Patent Images
1. A method of processing an image, the method comprising:
- receiving an input image;
filtering the input image to generate a filtered image;
generating one or more edge weights related to at least one edge of the input image;
generating an output image based on the input image, the filtered image, and at least one of the edge weights; and
outputting the output image.

Abstract
A system and method of reducing noise are disclosed. In one embodiment a system comprises an input configured to receive an input image, a filter configured to filter the input image to generate a filtered image, a weight generator configured to generate one or more edge weights related to at least one edge of the input image, a mixer configured to generate an output image based on the input image, the filtered image, and at least one of the edge weights, and an output configured to output the output image.
