IMAGE FUSION METHOD BASED ON GRADIENT DOMAIN MAPPING

摘要

The disclosure of an image fusion method based on gradient domain mapping, which comprises: inputting a plurality of to-be-fused images to a processor of a computer by an input unit of the computer, and performing the following steps by the processor of the computer: performing gradient domain transform on the plurality of to-be-fused images, extracting the maximum gradient modulus value in the plurality of images corresponding to each pixel point in a gradient domain as the gradient value of final fused image at the pixel point, traversing each pixel point to obtain the gradient domain distribution of the final fused image, and mapping the plurality of to-be-fused images into the same spatial domain according to the obtained gradient domain distribution to obtain a fused image; and outputting the fused image obtained by the processor by an output unit of the computer.
