Patent ID: 8150196

Claim:
A method of filtering noise in a video image, comprising: receiving a first video image, a second video image and motion information wherein said first image is an image to be filtered and said second image is a filtered image wherein said second image is temporally related to said first image; for at least one pixel in said first video image: selecting at least one neighbor of said pixel from said first video image and selecting at least one neighbor of said pixel from said second video image, wherein selection of said neighbors from said first video image and said second video image is based on said motion information; selecting a subset of said neighbors wherein said subset is less than or equal to a sum of neighbors from said first video image and said second video image; determining a plurality of weights for a weighted average and storing said weights in a lookup table; determining a weighted average of said subset of said neighbors and said pixel; outputting said weighted average as a filtered pixel of said first video image.
