A new infrared image enhancement algorithm

In order to solve the problem of low contrast, fuzzy details and poor visual effect of infrared image. In this paper, a scheme for infrared image enhancement is proposed, which solved drawbacks of the histogram equalization algorithm that loss detail information of image and some areas are bleached, greatly improved the visual effect of the infrared image. Firstly, Bilateral filter is performed on the original infrared image, we can obtain a base layer and a detail layer. At base layer, histogram equalization algorithm is applied to enhance the global contrast. Finally gamma correction is used to enhance detail layer coefficient and improve the visual effect of the infrared image. Through simulation on MATLAB, the results show that the proposed scheme could noticeably enhance contrast and greatly reduce the phenomenon of bleaching in some areas caused by the histogram equalization, obtaining a better infrared image enhancement effect, at end.
