Abstract:
In a computer having a processor which executes instructions stored in memory, a method for generating panoramas from two dimensional images, comprising the steps of:storing at least two rectilinear images in a computer memory; blending said rectilinear images to create a panorama; said blending of said rectilinear images to create a panorama comprising the steps of: (a) constructing a Laplacian pyramid for the overlapping images in an image overlap region where said images overlap, said Laplacian pyramids having a plurality of levels; (b) determining the coarsest level resolution level of the Laplacian pyramids for each of said images; (c) constructing a blend mask from the image overlap region for said plurality of overlapping images, said blend mask being a Gaussian pyramid; and (d) combining said Laplacian pyramid and said Gaussian pyramids to blend said images in said image overlap region.
