在人类视觉系统对比敏感度函数的基础上，提出了机器视觉系统对比敏感度函数的模型。与人眼相似，我们将神经节细胞感受野的概念应用于人工光敏元件。在此基础上，引入了数字图像局部对比度和整体对比度的定量度量。我们认为，对比敏感度阈值在参数空间对比度-空间频率中形成一条等值线。该模型，在计算机视觉系统中实现，已经比较的对比敏感度研究的结果，直接与人类视觉系统进行，并表现出良好的匹配。
The model of contrast sensitivity function (CSF) of machine vision system, based on the CSF of the human visual system is proposed. By analogy with the human eye, we employ the concept of ganglion cell receptive field to the artificial light-sensitive elements. By further following this concept, we introduced quantative metrics of local and global contrast of digital image. We suggested that the contrast sensitivity threshold forms an iso-line in the parameter space contrast – spatial frequency. The model, implemented in a computer vision system, has been compared to the results of contrast sensitivity research, conducted directly with the human visual system, and demonstrated a good match.
