红外图像灰度直方图统计分析的研究

数字图像的直方图反映了其像素强度值的分布情况.作为图像处理中最简单和最有用的一种工具,直方图方法用于许多图像操作中,例如对比度拉伸、直方图均衡化等.用灰度直方图方法对150幅不同类型的红外图像进行了统计分析.结果表明,在这些图像中,大多数图像没有灰度值小于16的像素,或者此类像素数量很少.这意味着A/D数据流的低4位对红外图像质量的影响较小.

Statistical Analysis of Infrared Images Using Gray Scale Histogram

The histogram of a digital image shows the distribution of its pixel intensity.As one of the simplest and most useful tools in image processing,the histogram method is used in a lot of image operation,such as contrast stretching and histogram equalization etc.150 different infrared images are analyzed statistically by using the histogram method.The analysis result shows that there are none or few pixels with a grey scale value less than 16 in most of these images.This implies that the lowest 4 bits in the A...
