Abstract
A method for composition of two digital images which overlap in an overlapping pixel region, including adjusting the pixel color values of at least one of the digital images so as to produce resulting digital images including at least one modified digital image, and combining the resulting digital images in the overlapping pixel region by taking weighted averages of their pixel color values. There is also described a method for feathering two digital images which overlap in an overlapping pixel region, including aligning the digital images so as to approximately register them in the overlapping pixel region, determining three curves, one of which is a leftmost curve, another of which is a middle curve and another of which is a rightmost curve, and at least one of which is not a straight vertical line, the curves extending from the top to the bottom of the overlapping pixel region and lying within the overlapping pixel region, and the middle curve lying between the leftmost and the rightmost curve, and combining the digital images by taking a weighted average of the pixel color values, in such a way that the weights used are a value above 50% of image A and a value below 50% of imag…
