Non-uniform light distribution problems often arise in the real world images taken by digital device. In this paper, we propose a fast and efficient technique for color image enhancement using fast and adaptive bi-dimensional empirical mode decomposition. This method removes non-uniform light information from the illumination plane of color image efficiently. And then, we apply a brightness correction method to compensate the light information. The experimental results show that the proposed approach can effectively enhance the color image. Besides, this method requires less computing resource and is well suitable for implementing on the real-time system.
