| 摘 要： | 提出一种基于离散Beamlet变换的快速新型线特征检测算法,可检测出任意方向、位置、长度的线性信息,并使线性特征的完整性和准确性都得到很好的保持。给出一种带有方向信息的多尺度的Beamlet基,利用Beamlet多尺度分析的思想,对传统的基于Bresenham直线生成的算法进行改进,通过设计偏差函数与优化的二进递归分解结合,对图像进行快速离散Beamlet变换。通过简单算法对图像的线特征进行提取,实验验证了该方法使用效果优于其他传统特征检测算法。

| Abstract: | A new method of linear feature detection based on Beamlet transform is proposed, which can detect lines with any orientation, location and length. An approach to multiscale image analysis, i.e. Digital Beamlet Analysis, has been made so as to extract lines perfectly. The traditional linear feature detection algorithm based on Bresenham has been improved via fast Digital Beamlet transform that combining designed deviation function with BD-RDP. The integrity and accuracy of linear feature are kept. Experiment... |
