A fast ground object recognition method for aerial images, taking airports, oil depots, harbors, etc., as research objects, is proposed in this study based on BRISK and the visual saliency detection. According to the characteristics of aerial images, such as high resolution and complex background interference, saliency detection is applied to select the candidate object region where the target may exist. Therefore, it can reduce the searching range effectively. And then, BRISK matching method is used to recognize the object efficiently. A variety of experiments under different interference factors are carried out based on the typical object database of aerial images in this study. Experimental results show that the proposed algorithm can not only maintain the validity of BRISK features under the conditions of rotation, scale, illumination and viewpoint changes, but also shorten the matching time, satisfying real-time demand.

Based on the professional theory course evaluation of partial scores of 30 teachers done by the supervisions, the study uses SPSS software and the factor analysis method to evaluate the quality of teachers' professional theory teaching and finds out the key effect factor of evaluating teaching quality. Then the study puts forward some countermeasures to improve the teaching level of teachers and evaluate t scientifically the teachers’ teaching quality.
