Firefly: A hardware-friendly real-time local brightness adjustment method

Brightness adjustment is an important part of image enhancement, but some of the best brightness adjustment methods in terms of result quality are too complex to run in real-time and many are not suitable for hardware implementation. In this paper a fast learning-based and hardware-friendly method for local brightness adjustment is proposed that in real-time obtains results of higher quality than some of the best methods. The results are presented and discussed. The source code is at http://www.fer.unizg.hr/ipg/resources/color constancy/.
