A fast contrast enhancement method for forward looking infrared imaging system

In this paper, a fast contrast enhancement method for forward looking infrared imaging system is proposed. Histogram equalization and plateau equalization are widely used for infrared imaging system. However, they often introduce the significant change in luminance which causes luminance saturation and failure in object tracking. Proposed method uses an adaptive histogram redistribution based on histogram partitioning to prevent the side-effect due to the over-enhancement. The experimental results show that proposed method has better performance compared with conventional methods.
