A New Improved Hierarchical Model of Image Fusion

The basic conceptions of image fusion are given in the paper and the hierarchical model of image fusion is supplemented. Some preprocessing segments, such as the re-sampling of image, spatial and temporal registration, are introduced to the improved model. Together with the results obtained from single-image processing, the fusion results of previous hierarchy are input to the next fusion layer. The previous fusion achievement can be effectively utilized. The evaluations to the fusion results are feedback to the hierarchical model. The fusion algorithms and criteria are adjusted according to the evaluations. Some other pending-solving questions in image fusion are given.
