| 1. | Secondly , this paper mainly put forward different grey level threshold value segmentations of plane target after brief analyse the smooth and sharp image of image strengthen technology , segmentation for the overall situation , adopt the maximum variance method , the maximum entropy combine with adaptive threshold selection method , the maximum variance ration between two classes and in two classes ; segmentation for the part situation , has adopted the adaptive threshold value method ; to background more complicated segmentation , have adopted the two - dimentional maximum entropy method
其次,在简要的分析了图像平滑和锐化的图像增强技术后,重点研究了飞机目标的灰度分割,提出不同的灰度阈值分割方法进行图像分割,对于全局分割,采用了最大类间分割法、最大熵与一致性准则相结合法、最大类间类内方差比法;对于局部分割,采用了自适应阈值法;对于背景较复杂的分割,采用了二维最大熵法。 |
