摘　　要：本研究采用由CIE1976 LAB色空间发展而来的LCH颜色空间和基于人眼视觉系统(HVS)的对比敏感度函数(CSF),建立了LAB模式下彩色图像滤波流程,对彩色图像进行LCH-CSF视觉滤波,并进行了彩色图像色差分析。研究表明,基于LCH颜色空间的对比敏感度函数模型,可以满足设备无关条件下彩色图像频域处理的要求。依照所构建的图像滤波流程,进行CSF视觉滤波,可以实现不同观察距离、不同图像尺寸下的良好视觉效果。In LCH color space which stems from CIE1976 LAB color space, using Contrast Sensitivity Function （CSF） based on Human Visual System （HVS）, a filtering processing flow of color image was constructed. Some color images of LAB model were filtered with the filter generated from LCH-CSF, and the color difference between the filtered images and the originals was analyzed. The model of CSF under colorimetrical LCH space can meet the demand of device independent color image processing in the frequency domain. Image processing with CSF filtering flow can simulate the visual effect of image under different viewing distance and different image size.
