Images acquired by heterogeneous image sensors may provide complementary information about the scene, for instance, the visual image can provide personal identification information like the facial pattern while the infrared (IR) or millimeter wave image can detect the suspicious regions of concealed weapons. Usually, a technique, namely multiresolution pixel-level image fusion is applied to integrate...
Image fusion is studied using a very basic and reasonable mathematical model for the observed images. The model attempts to characterize the statistical aspects of the problem, including the impact of random distortions, like noise. The image fusion problem is posed as an estimation problem where the best fusion algorithm minimizes the mean square error between the fused image and the true scene....
