Abstract: An alignment method for high dynamic resolution imaging searches and detects features in an image and parameterizing the features. Then differently exposed images are compared by comparing the features. Additionally the method detects features in an image, performs shape adaptive filtering using scaling pyramids, determines trajectories, calculates a range of characteristics for each unit in the image, and compares characteristics of paired units to select or eliminate the pair. Paired unit characterization selects unit pairs, selects unit pairs by statistical analysis, performs cluster analysis, calculates alignment parameters, and performs additional correction of the alignment parameters. The brightness channel is used for objects detection.
