| 摘 要： | 结合高空间分辨率遥感影像的特点,利用数学形态学方法,选取具有不同尺度和包含全部方向的结构元素,设计一种多尺度全方位形态学边缘检测算法,并采用峰值信噪比方法代替均值以自适应地确定尺度权重.实验结果表明:与传统Canny算子和结构元素尺度形状单一的形态学边缘检测算法相比,本算法解决了噪声抑制和精细边缘提取的矛盾,检测出的图像边缘清晰,而且抗噪性能强.边缘检测结果可用于遥感影像地物几何特征和纹理特征提取. |

| Abstract: | Based on the characteristics of remote sensing images with high spatial resolution and mathematical morphology(MM) methods,a multi-scale and omnidirectional MM edge detection algorithm were developed by using multi-scale omnidirectional structure elements.In this algorithm,the peak signal-to-noise ratio(PSNR) technique was adopted to replace the method with fixed mean for acquiring the self-adaptive scale weights.Experimental results suggest that: the proposed algorithms,comparing with the traditional Canny... |
