摘    要:阐述了图像质量客观度量准则的概念,给出了4种典型客观度量准则:归一化最小方差、保真度、相关度和信息率的性能评价函数,理论推导了它们之间的相互关系;针对光电成像系统的能量分辨率损失和空间分辨率损失仿真图像,计算并比较了4种客观度量的输出结果,验证了客观度量函数在性能评价中的合理性。

关 键 词:光电成像系统  客观度量准则  保真度  相关度  信息率

Abstract:The concept of objective measure criteria of image quality is briefly illustrated. The performance evaluation functions of the four types of measure criteria: normalized minimum variance, fidelity, correlation, information rate are given respectively, and their relationship are analyzed theoretically. Focusing on the spatial and energetic resolution loss simulation image of electro-optical imaging system, the output results of objective measure functions is calculated and compared. Finally, the reasonable characterization of the objective measure function in performance evaluation is validated.
Keywords:Electro-Optical imaging system  objective measure criteria  fidelity  correlation  information rate
