Application background The mean filter using the neighborhood averaging method is applied to remove the noise of the particles in the image obtained by the scanning. In the field, the noise is suppressed effectively, and the fuzzy phenomenon is caused by the average, and the fuzzy degree is proportional to the radius of the field. Key Technology Noise is an important cause of image interference. There may be a variety of noises in the practical application of a picture, which may be generated in the transmission, and may be generated in the process of quantification. According to the relationship between noise and signal, it can be divided into three forms: (x (F, y), G (x, y), (x), n (, y).1) additive noise, the signal of this kind of noise from the input image has nothing to do noisy image can be said for f (x, y) = g (x, y) + n (x, y), the noise in the channel and optical camera tube camera scan image generated noise belongs to this kind of no
