Abstract: The lateral inhibition network has the function of enhancing the contrast and outstanding the edge and the outline，but its anti-noise capability is poor.In order to enhance the image with better anti-noise ability，this paper proposes a image pre-processing algorithm based on lateral inhibition and adaptive filter，which can not only outstands the image’outline，but also eliminates the noise by adaptively changing the model parameters accordingly to the local image’s mean，variance and the noise variance.Compared with the traditional image processing method，the simulation results show this algorithm can both enhance the image and effectively eliminate the noise，with a better vision effect.
