Patent ID: 8824833

Claim:
A method for image data fusion, comprising: receiving a first set of image data as at least one first data channel and corresponding to a first imaged first scene; receiving a second set of image data as at least one second data channel and corresponding to a second imaged second scene that at least partially overlaps said first scene in an overlap region, converting at least a portion of the first set of image data corresponding to the overlap region from at least one of the at least one first data channels formats into a plurality of first frequency subsets within a transform domain by applying a first forward transformation; converting at least a portion of the second set of image data corresponding to the overlap region from at least one of the at least one second data channels into a plurality of second frequency subsets within the transform domain by applying a second forward transformation; and producing a fused set of image data by replacing at least one of the plurality of first frequency subsets with a corresponding at least one of the plurality of second frequency subsets of a selected second data channel; wherein: each of the plurality of first and second frequency subsets correspond to one of a plurality of frequency sub-bands, and the converting and receiving steps are performed by an image processor, and the step of converting the second set includes filtering at least the data from the selected second data channel corresponding to the overlap region, and the first set of image data is received from a color camera and the second set of image data is received from a grayscale camera.
