| 中文摘要: |
| 在回顾视觉频率响应研究状况的基础上,以对比敏感度函数 CSF 为基础,在 LCH 色彩空间中,经过视觉观察实验,获取了人眼视觉系统对明度、彩度和色调角的频率响应(CSF 函数)。 研究结果对彩色视觉相关的图像处理、传播、压缩、图像质量评估等具有重要意义。 |
| 英文摘要: |
| Previous researches of visual frequency response were reviewed. Contrast Sensitivity Function ( CSF) of human visual system to lightness, chroma, and hue in LCH color space were obtained through visual tests based on the concept of CSF. The purpose was to provide reference for color image processing, communicating, compression and image quality evaluation etc. |
