摘　　要：针对传统伪彩色图像均衡化增强系统色彩灵敏度较低的问题,提出一种基于暗原色先验的伪彩色图像均衡化增强系统。系统硬件由初始化模块、伪彩色图像处理模块、伪彩色图像存储模块、伪彩色图像均衡化增强模块、伪彩色图像显示模块构成;系统软件配置为伪彩色图像均衡化处理软件,通过硬件与软件的结合实现了伪彩色图像的均衡化增强。为了验证基于暗原色先验的伪彩色图像均衡化增强系统的色彩灵敏度较高,将该系统与基于运算图像矩阵的伪彩色图像均衡化增强系统、基于自适应阈值计算模型的伪彩色图像均衡化增强系统、基于最大类间方差的伪彩色图像均衡化增强系统、基于单精度浮点指令的伪彩色图像均衡化增强系统进行对比实验,实验结果证明,所提系统的色彩灵敏度最高,更适用于伪彩色图像的均衡化增强。In view of the low color sensitivity of traditional pseudo-color image equalization enhancement system,a pseudocolor image equalization enhancement system based on dark channel prior is proposed. The system hardware consists of the initialization module,the pseudo-color image processing module,the pseudo-color image storage module,the pseudo-color image equalization enhancement module and the pseudo-color image display module,while the system software is pseudo-color image equalization processing software. The equalization enhancement of pseudo-color images is realized by the combination of hardware and software. In order to verify the high color sensitivity of the pseudo-color image equalization enhancement system based on dark channel prior,comparison experiments are performed between the system and the pseudo-color image equalization enhancement system based on operation image matrix,the pseudo-color image equalization enhancement system based on adaptive threshold computing model,the pseudo-color image equalization enhancement system based on maximum between-class variance and the pseudo-color image equalization enhancement system based on single precision floating-point instruction. The experimental results show that the proposed system has the highest color sensitivity and is more suitable for pseudo-color image equalization enhancement.
