| 摘 要： | 针对舰船目标和海杂波轮廓结构的不同，提出了基于边缘链码高阶分形特征的舰船目标检测算法，算法利用相对链码对5类舰船目标轮廓进行编码，分别计算分形维和缝隙，得到了舰船目标的4个分形特征的范围。实验结果表明边缘链码的4个分形特征能有效区分舰船目标和海杂波。 |
| 关 键 词： | 链码 高阶分形特征 缝隙 目标检测 |

| Abstract: | An algorithm based on edge chain code high-order fractal feature for ship target detection based on the contour difference of ship target and sea clutter is put forward in this paper. The algorithm codes the contour of five kinds ship based on relative chain code. It computes fraetal dimension and lacunarity respectively, and gets the range of ship target four fraetal feature. The experimental result shows that the four fractal feature can identify ship target and sea clutter effectively. |
| Keywords: | chain code high-order fractal feature lacunarity target detection |
