In this paper, an efficient technique is proposed for real-time enhancement of video containing inconsistent and complex conditions like nonuniform and insufficient lighting. Beyond providing digital tools for video enhancement, this method provides a better approach to enhance a video in low lighting conditions without any loss of color information. This approach is based on histogram manipulations on La*b* color model of the video frame. This algorithm provides an effective way for video enhancement with simple computational procedures, which makes real-time enhancement for homeland security application successfully realized. Simulation is done on videos taken under bad lighting conditions and results are presented.
