This study proposes a new calculation method for generating real nighttime lamp-lit images. In order to improve the color appearance in the prediction of a nighttime lamp-lighted road scene, the lamp-lit image is synthesized based on spectral distribution using the estimated local spectral distribution of the headlamps and the surface reflectance of every object. The principal component analysis method is introduced to estimate the surface color of an object and the local spectral distributiondoi:10.1109/tvt.2004.825790 fatcat:6q2js4nw65hozmoy5r2fmuw5na
