Abstract
A method for fusing a primary image (P) and a secondary image (S) into a target image comprises determining a local noise level of a region of the primary image; deriving a low-frequency, LF, component (PLF) from said region of the primary image and a high-frequency, HF, component (SHF) from a corresponding region of the secondary image, wherein the LF and HF components refer to a common cut-off frequency; combining the LF component and the HF component into a target image region, wherein the HF component's relative contribution to the target image region increases gradually with the local noise level; and repeating the preceding operations and merging all output target image regions thus obtained into the target image. A system implementing said method is also provided.
