摘要
为了增加TM遥感数据单波段信息量和视觉感知力,实现定量模拟TM遥感影像各波段反射率,提出一种TM遥感影像图像处理新方法,即在不破坏原有波段光谱特征的基础上重构TM波段反射率模拟图像。选取图像质量评价指数进行客观定量评价分析,实验结果表明:单波段信息熵值平均增加1.35,获得的均方误差系数和峰值信噪比值有明显变化,均方误差值平均减少11.2,重构的模拟单反射率TM影像灰度级离散程度集中,信息量丰富,图像增强变化和光谱信息优化程度都有显著提高。
This paper presents a new method for Landsat TM Image processing which can be used to quantitative simulating each band reflectance of TM image. On the basis of non-destruction of the original band spectral features, it improved single band information and visual sensitivity. The restructured Image quality were analyzed by image quality assessment indexes, and the results show that the image enhancement change and spectral information optimization degree of reconstructed Image have greatly improved.
