影象增强技术是一种重要的遥感图象判释技术,它利用不同的方法,增强有价值的目标物的影象,使目标物突出地显示出来,使原来不能区分或不易区分的目标物能够区分或者易于区分,从而提高判释效果。彩色合成是一种影象增强技术,它利用肉眼对彩色差异比对黑白差异(灰度差异)的分辩能力大得多的特点,用不同的颜色来显示多 Image enhancement technology is an important remote sensing image interpretation technology, which uses different methods to enhance the image of valuable objects, so that the target is prominently displayed so that the original can not be distinguished or difficult to distinguish the target Can distinguish or easy to distinguish, so as to improve the interpretation effect. Color synthesis is an image enhancement technique that utilizes the much greater characterization of the color difference by the naked eye over the ability to distinguish between black and white differences (gray level differences), with different colors to show more
