摘要
该文在分析图像的边缘细节提取与噪声消除相矛盾的基础上,提出了一种有效的滤波尺度自适应调整的小波边缘检测方法,并且给出了滤波尺度参数的调整策略。实验结果表明,该方法能有效提取图像的细节边缘,具有较好的抗噪声性能。
Analyzing the contradiction between edge detail detection and noise elimination,an effective method for deter-mining the scales of edge detection is presented,and the strategy of filter scale parameter adjustment is put forward in this paper.The experiments show that the proposed algorithm is effective in edge detection and suppressing noise.
