Abstract: In this thesis, adopting the character of grey histogram, grey level co-occurrence matrix and wavelet transform, three kinds of characteristic methods combineing can the purpose of the good realization classification.On the foundation of the feature extraction, this study accord to environment of MATLAB6.5 under of the nerve network tool box, RBF nerve network was put forward, which consider both the speed of recognition and the classification accuracy to recognize and classify the strip steel surface, This arithmetic can be the optimization project tothe real-time examining of the high-speed production line of strip steel surface defect image.
