Abstract

An efficient real-time video stream enhancement algorithm based on illuminance-reflectance model is proposed for improving the visual quality of digital video streams captured under insufficient and/or non-uniform lighting conditions. The paper presents computational methods for estimation of scene illuminance and reflectance, adaptive dynamic range compression of illuminance, and adaptive enhancement for mid-tone frequency components. This algorithm is an effective and efficient technique for image enhancement with relatively simple computational procedures, which makes real-time enhancement of digital videos successfully realized. It also demonstrates strong robustness and high image quality when compared to other techniques.
