| Abstract |
Color constancy is the ability to recognize the inherent object color invariant to surrounding illuminants. With the development of electric bulbs, there are various illuminant environments. It is an important process for image signal processing pipelines and has been studied for a long time. Most studies focus on spatial information of a single image. Several studies recently proposed the use of temporal features of high-speed video. Because light bulbs are supplied by AC (alternative current) power, the intensity varies sinusoidally with time, which can be captured with a high-speed camera. The temporal features of periodic variation were used for several color constancy studies. They showed the usefulness of temporal features. This review introduces various color constancy methods in spatial and temporal domains and compares the accuracy of illuminant estimation. |
