Abstract:
1. A method of processing a digital image with a computer having a digital image processing function to form an image pyramid having a first to a Nth number of pyramid image levels from a luminance image obtained from the digital image, the Nth number corresponding to a predetermined number of pyramid image levels or a number reached when a predetermined condition is met, the method comprising the steps of: a) generating a first level base image comprising pixel values at pixel locations arranged in rows and columns based on an initial level base image, which is the luminance image obtained from the digital image, the first level base image having a smaller resolution than the initial level base image; b) generating a next level base image by: c) generating a subsequent level base image to an Nth level base image by repeating step b) until the Nth number of pyramid image levels are generated.
