摘要
为了解决用POSHE算法对红外图像进行增强处理时存在的过增强等问题,提出了一种基于最优灰度分布拟合的直方图变换方法,并通过MATLAB仿真对其进行了试验验证。结果表明,该方法不仅可以有效缓解过增强问题,消除经POSHE算法处理后产生的块效应现象,而且还可以抑制制冷型红外探测器的"冷反射"图像。本文方法在增强红外图像对比度的同时,能够有效保留红外图像的整体信息,并且具有较好的视觉效果。
To solve the problem of excessive enhancement when a POSHE algorithm is used to enhance infrared images,a histogram transform method based on ＇optimal gray-level distribution＇ fitting is put forward and is verified in a MATLAB simulation experiment.The result shows that the method can not only alleviate the problem of excessive enhancement and eliminate the block effect phenomenon due to processing by the POSHE algorithm,but also inhibit the ＇cold reflection image＇ of a cooled infrared detector.The whole information of an infrared image can be retained and form good visual effectiveness while the contrast of the image is enhanced.
