An Adaptived Output Window Technique Based on Gray Redundance for Infrared Image
基于灰度冗余的红外图像自适应输出窗技术

An adaptive output window technique based on gray red undancy for infrared image is proposed in order to overcome the disadvantage of infrared image gray distribution.The adaptive output window threshold is calcula ted from the histogram,if the pixels sum of the same gray level is zero,this gra y level is compressed.Those gray levels which pixel sum is less than the thresho ld are replaced by gray level of the threshold.Then effective gray-levels are d istributed equidistantly .This algorithm can eliminate gray redundance and no gr ay-level lost.The results show that the image quality has been improved.Theis a lgorithm achieved real-time processing.
