A FILTERING METHOD OF SCENE MATCHING REFERENCE IMAGE
Long Ma · Aerospace Shanghai · 2000
Scene matching reference image is contrasted with real time image in their feature. Common filtering methods of real time image are analyzed. It is considered that these methods of filtering are not fully suitable for reference image. Then, a new two step filtering method has been extracted according to the feature of reference image. The first step one is homomorphic filtering and the second step is minimum variance filtering. This method is suitable for the filtering of bump; it also considers the recovery and intensify of image. It is proofed by a simple experiment, that this method is valuable to image preprocessing of scene matching reference
