摘　　要：给出了PE算法平台值取法的依据和算法用C语言实现的步骤 ,并结合具体的实例进行试验 ,比较和分析了这三种算法能有效压缩信息提高图像对比度的原因 。This paper described the principle of HE, HP and PE algorithms based on histogram, and provided the useful range of plateau values and the key steps of implementation with C language for PE algorithm, and analyzed the reasons why the three algorithms could compress information and increase contrast with concrete examples. The result showed PE algorithm including HE and HP algorithms as extreme cases with reasonable plateau could work well in thermal image display with high dynamical range.
