摘要 通过分析现有的一些方法,提出了一种基于自适应脊波变换的边缘检测方法。这种方法以脊波变换为理论基础,具有多方向和多尺度性,能对图像中的不同方向的边缘特征进行有效的表示和检测。实验表明,对于边缘主要表现为直线而其他位置光滑的图像,该检测方法抗噪声更强,定位更准确。 A method for edge detection based on adaptive ridgelet transform was proposed. It could present and detect edges efficiently with different directions in an image. Experimental results show that the proposed method locates edges more precisely for noised images with straight edges.
