Color Image Fundamentals Color perception is a psychophysical phenomenon that combines two main components: 1. The physical properties of light sources (usually expressed by their spectral power distribution, SPD) and surfaces (e. g. , their absorption and reflectance capabilities). 2. The physiological and psychological aspects of the human visual system (HVS). 12/1/2020 COMSATS Institute of Information Technology, Lahore Digital Image Processing CSC 331 2
