| 摘 要： | 文章首先利用二进方块中Beamlet基的对称、平行等几何性质对离散Beamlet基进行分类;然后通过定义一个新的二进方块统计量和建立一个新的能量函数,对Beamlet变换方法中利用BD-RDP提取线特征的算法进行改进.通过实验对比,该算法进一步减少了运算量,提高了线特征提取的速度,且对复杂结构图像中的线特征提取效果更为清晰.

| Abstract: | A modified algorithm which utilizes the BD-RDP algorithm based on Beamlet transform is presented in this paper.It classifies Beamlets by the Beamlets' geometric properties(symmetry and parallel),defines a new quantity(dyadic square statistic) and establishes a new energy function.Experimental results demonstrate the reduction of the computation and the improvement of the speed.These results also demonstrate the effectiveness of the method in the complicated real images. |
