It is unclear that what color descriptors best fits feature matching of aerial remote sensing Bayer real-color image. To analyze variation of imaging of the aerial image and algorithm characteristics of color descriptors, a theoretical analysis of invariant properties of color descriptors was presented. The effect and applicability of descriptors were verified and analyzed by three experimental methods which are evaluations of simulation data, different categories images and general applicability of task. The theoretical and experimental results show that RGBSIFT has best applicability for the feature matching of aerial Bayer real-color image. The usefulness of color descriptor is category-specific. ©, 2015, National University of Defense Technology. All right reserved.
