【Abstract】 How to realize the automatization of ferrographic diagnosis by PC image processing is one of the research targets in the development of ferrographic technique,and in order to reduce noise and simplify data processing, the preprocessing of original images is the necessary step,which directly affects the following processing. In this paper,some methods of processing original ferrographic images such as smoothing,filtering,and threshold method are discussed,and a new method-debris selection is developed,which is based on the iterative convolution in the whole map with a blank, size variable window. These methods are applied to the processing of a real ferrographic image and some satisfactory results are obtained,which verifies the validity of the methods.更多还原
