ABSTRACT:
A method of blending a pair of images, each image comprising a plurality of pixels having an intensity. A blending edge is determined for each image, each blending edge comprising at least one group of pixels, with each pixel at a pixel position, and an average intensity of pixels of the blending edges is determined at each pixel position. The method includes determining a scaling factor based on a relationship between the average intensity and the intensity of the pixel of the at least one group of pixels of the blending edge at each pixel position of each image. A blending area is determined for each image, each blending area comprising at least one group of pixels having a pixel at each of the pixel positions. The intensity of the pixel at each pixel position of the at least one group of pixels of the blending area of each image is scaled with the corresponding scaling factor.
