提出了一种改进的灰度共生矩阵肝脏CT 图纹理特征分析方法，即首先确定图像ROI 区域，接着构造一个新的能综合反映共生矩阵各角度信息的灰度共生矩阵，然后提取基于该矩阵的纹理特征参数。通过实验验证，上述方法是分析肝脏CT 图的一种快速有效的纹理特征分析方法，对其他特定类别图像的纹理特征分析有参考意义。Radon 变换检测航迹, 并对结果进行了优化. 与现有的检测方法相比, 该方法针对性强, 复杂度低. 使用该方法对实际航拍图片进行了检测实验, 取得了很好的效果.-Track propose a novel detection method based on the optical image. Firstly texture analysis method to determine whether they contain to be detected in the track area, and then by using stripes enhancement algorithms to determine the area, highlights track characteristics, and finally the use of Radon transform to detect track, and the results were optimized. Compared with existing detection method, which targeted, low complexity. use this method to detect the actual experiments conducted aerial images, and achieved good results.
