22 October 2010Research on infrared image enhancement algorithm based on histogram
Infrared image often has the defects of low contrast and high dynamic range. Image enhancement technology is very
important for infrared images. In this paper, several methods were introduced to improve the quality of infrared images.
At first, images from IRFPA must be pre-processed by the algorithm of blind compensation and non-uniformity
correction (NUC). Then, the image was enhanced by the algorithm of direct gray scale transformation and plateau
equalization (PE). The quality of the image was enhanced effectively. However, the noise was also amplified. At last, the
image noise was suppressed by using median filter. The experiment result indicates that infrared image enhancement
algorithm can not only enhance image contrast effectively but also keep the detail information of original infrared image
well.
