Double-spectral Imaging In The Dim Light Of Automatic Image Registration

Image registration is a classic problem in image processing, and it is extensively applied to the field of computer vision, pattern recognition, medical image processing and remote sensing information processing. It is the precondition of image fusion.In the dissertation, on the basis of the analysis on the double channel's low-level and ultraviolet light dual-band fusion color night vision method, a technique of double channel's low-level light and ultraviolet dual-band image registration research is investigated. We reviewed the main arithmetic of registration. Former numeral shift registration which need human interfere was deeply researched. Considering the characteristic of the low-level and ultraviolet light and the system, we proposed new registration arithmetic of dual-band image based on the pixel's spatial relativity. Based on the DSP hardware platform, the software programs are designed and the automatic processing of the algorithms is realized.
