对图像进行灰度量化时，容易把颜色不同而灰度相同的像素归为一类，造成量化误差而影响评价结果。基于HSV颜色空间，通过统计样本数据，结合人眼观察彩色的视觉特性，确定了颜色量化范围，建立了适合伪装特点的颜色直方图，利用距离函数进行了目标颜色特征的伪装效果评价。实验结果表明，利用改进的量化颜色直方图评价目标伪装效果，能够客观地表征目标及其背景的颜色特征，伪装效果的评价结果与人眼观察结果吻合，可以作为一种评价目标颜色特征伪装效果的量化方法。

The pixels of the different colors and same gray can be assorted easily, which can result in the quantization errors and impact the evaluation results, when the grayscale is quantified. Based on the HSV color space, combining with the visual characteristics of the human eye, the quantitative range of the color is determined and the color histogram suitable for the camouflage characteristics is established. The camouflage effectiveness of the target color characteristics is evaluated using the distance function. The experimental results show that the evaluation of the camouflage effectiveness using the improved quantitative color histogram can objectively evaluate the target and its background color characteristics, and evaluation results are consistent with the results of human eye. This quantitative color histogram can be used as a quantitative method for evaluating camouflage effectiveness of the target color characteristics.
