Research on Frequency Response Characteristic of Color Vision in LCH Color Space
Packaging Engineering（2012）
Abstract
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.
