  • The infrared images that are captured at long range usually have low contrast, low brightness, and small hot objects of interest.A novel adaptive histogram-based equalization was put forward to enhance the contrast of infrared images in order to overcome the defects of infrared image itself. It can automatically generate a hybrid cumulative histogram based on two different pieces of information about the image histogram.The proposed adaptive equalization approach can automatically realize image equalization.Experimental results demonstrated that the approach proposed in this paper can improve the contrast of infrared images,and the effect is more obvious to the small objects embedded in infrared images.
