| 摘 要： | 根据波浪图像的纹理特征,提出了一种新的基于分水岭和Radon变换的波向检测算法,该方法利用波浪纹理特征,选择效率高且易于实现的分水岭变换,对图像波谷进行分割,提取波谷形态方向并推算出带有±180°方向模糊的波浪方向;截取波浪纹理图像并生成时栈图像,通过Radon变换去除方向模糊,实现波向的有效检测.仿真实验结果表明,该算法简单有效,有利于提高波向检测的精度和效率.

| Abstract: | To extract wave direction from sea surface images, a new method is proposed, which is based on a combination of watershed transform and Radon transform. Using the feature of sea wave images, this method first selects a watershed transform to segment the image into wave trough regions. Then the wave direction that has an associated 180 degree ambiguity is calculated from the trough areas. Meanwhile, a time stack image is generated from the frames and processed by Radon transform to find the forward wave dire... |
