摘要
针对Hough变换累积矩阵存在的峰值扩散现象,提出了一个新的峰值检测方法。在对累加器参数空间进行分析的基础上,在局部最大值周围区域,选用每列有效累积单元个数进行函数拟合,从而得到最佳的峰值参数。实验结果验证了方法的有效性,与选用单元累积值的方法相比,对图像噪声具有更好的鲁棒性。
In order to deal with the problem of peak expanding of accumulator,a method of peak detection for Hough transform is proposed.By analyzing the distribution of accumulator cells around the local maximum,the count of cells is used for interpolation.The accurate peak is detected.Experimental results validate the proposed method.Compared with the traditional method,this method is robust for the image noise.
