摘要：Illumination estimation is an important for color constancy computation. Existing algorithms can be divided into two groups: physics-based algorithms and statistics-based approaches. In this paper, the advantages of the physical approaches are integrated. At first, according to the physics-based Grey-Edge framework, several approaches can be generated in a systemic way. Then the estimated results of these physical approaches are fused as the final result. The experimental results show that this combined algorithm is effective and can achieved much better color constancy result.
