摘要
传统的波浪波长和方向分析技术是谱分析。本文从海洋波浪图像直接作图像纹理分析,在图像的每一个处理窗口,以海浪图像灰度极值点大小、个数的分布和灰度共生矩阵为基础,构造了借以区分不同海浪波长和方向的纹理测度,实现提取海浪波长和方向信息。
The classical analysis technique for ocean wave length and direction is the spectrum analysis. In this paper, A new texture analysis technique for ocean wave image performed in the spatial domain directly is presented. For every processing window, based upon the distribution of local extremes and the grey level co-occurrence matrix, the texture measures to discriminate the different kinds of ocean wave lengths and directions are constructed. Finally, the information of ocean wave lengths and directions is extracted.
