摘要
根据波浪图像的纹理特征,提出了一种基于数学形态学图像分割的波向检测方法,该方法首先利用顶帽变换和底帽变换,得到增强的波浪纹理图像,然后对图像波谷进行应用标记的分水岭分割,最后利用波谷形态方向提取出波浪方向,实验结果证明该算法能够有效地实现波向检测。
To extract wave orientation, a new method with image segment is introduced, which is based on mathematical morphology. This method provides a combination of top-hat and bottom-hat transform to enhance the feature of sea wave image; the image was segmented into trough regions by marker-controlled watershed transformation; the wave orientation was calculated from trough areas. The simulation results show that this method is effective for extracting the sea wave orientation.
