  • 灰度信息

例句与用法

  • Usually , gray information is taken into account only in the pixel - dependent unsupervised algorithm , ignoring the characteristics of neighboring pixels
    基于像素的非监督变化检测方法,通常只考虑差异图象灰度信息,没有考虑其邻域特征。
  • Not only does this method take gray information into account but it also make use of image feature . compared with conventional methods , this method gains a better accuracy , efficiency and reliability
    这种方法不仅考虑灰度信息而且顾及影像特征,利用该方法匹配的结果在精度、速度、可靠性方面比传统方法有明显的提高。
