In order to solve such problems as background noise amplification, excessive image edge enhancement and ring effect in the output image caused by the difficulty of the existing self-adaption image enhancement algorithm in identifying the smooth and fine areas of an image, a self-adaption image enhancement algorithm based on rule fuzzy inference system is proposed in this paper. Firstly, the pixel field of the image to be enhanced is locally and statically analyzed to obtain the low-frequency component of the image; secondly, five logic rules are defined and meanwhile the local statistical information is combined with the local standard deviation to establish the rule fuzzy inference system so as to calculate the contrast gain factor and accordingly complete the self-adaption enhancement of the image and optimize the pixel field dimension. The simulation result shows: compared with existing contrast enhancement technology, the proposed technology has better visual enhancement effect and can obviously eliminate ring effect.
