Image Dynamic Range Remapping Algorithm for Dual Energy X-ray Security Inspection Machine
针对双能X射线安检机生成的图像无法在普通显示器上呈现所有细节的问题,提出一种基于多尺度局部边缘保持滤波(LEP)的色调映射算法.首先,将从X射线安检机获取的高能和低能图像,按照各自穿透特点匹配权重因子进行融合;其次,对融合图像进行自然对数变换,使用LEP滤波获得基础层图像,再通过作差方式获取细节层图像和tanh函数增强,对增强后的细节层图像进行相加融合;最后,进行负指数变换和灰度线性拉伸后得到尽显细节的低动态范围图像.实验结果表明,文章所提算法在…查看全部>>
A color tone mapping algorithm based on multi-scale local edge preserving filtering(LEP)is proposed to address the issue that images generated by dual energy X-ray security inspection machines cannot present all details on regular displays.Firstly,the high-energy and low-energy images obtained from the X-ray security inspection machine is fused by matching weight factors according to their respective penetration characteristics.Secondly,natural logarithmic t…查看全部>>
