By defining a region smoothness measure, the method firstly enhances peak-valley feature of image histogram by fuzzy set technique, and then segments image using adaptive multi-thresholding method.
该方法通过定义图像的平滑性测度,采用模糊增强技术对图像的灰度直方图进行增强,然后在增强的直方图上,利用自适应多阈值分割方法进行图像分割。
When used by pilots in describing off-airway routes, points defining direct route segments become compulsory reporting points unless the aircraft is under radar control.
在被飞行员用于描述偏置航路时,除了在雷达控制的情况下,确定直线航段的导航点成为必报点。
