Abstract :
Owing to the colour variations resulting from illumination changes, many colour-based digital image processing techniques have yet to demonstrate stable performance. Proposed is an image-based colour-temperature estimation method considering camera characteristics for colour constancy. The performance of the proposed method has been validated through experiments.
