Paper Abstract

A new algorithm which is suitable for FPGA to the real-time infrared image enhancement is proposed in this paper. In order to reduce Infrared image noise, we use the accumulation of the combining sequential neighbor frames, and use the nonlinear expanding of gray histogram to enhance contrast ratio. This kind of algorithm has considered infrared image characteristic and vision characteristic of the human eye synthetically, and guarantee real-time character of image process, at the same time, also give consideration to the advantage of the FPGA design. This method can be realized easily on hardware without damaged enhancement result. Finally, quality of enhanced image is evaluated through a model. It has verified the enhancement result of this kind of algorithm, and offered reliable assurance for further treatment of the infrared image. Use in the image system of the infrared video, the effect of image Enhancement is obvious.
