微光夜视仪分辨力客观测量方法研究

Study on measuring objectively for resolution of low-light-level night vision systems

利用灰度 梯度共生矩阵模型对微光夜视仪分辨力测量图像的纹理特征进行了分析 ,通过对大量图像的 5个纹理特征参数的计算 ,结果表明 ,这些参数能对微光夜视仪分辨力测量图像的纹理特征作出有效的客观评价 ,此计算结果与人眼的观察结果具有较好的一致性。

A gray level gradient cooccurrence matrix model is applied for the texture analysis of an image measuring low light level night vision system resolution. And 5 texture parameters are calculated by using this model for a good deal of images. This result shows that these parameters can evaluate objectively for the texture character of an image for measuring resolution of low light level night vision system. And it's consistent with human subjective evaluation.
