摘要
阐述了图像分形维和多尺度分形特征的概念,提出了一种多尺度分形目标检测方法。实验证明,自然背景与人造目标所在区域的多尺度分形特征差别非常明显。对于舰船目标检测,给出方法的检测结果稳定,优于边缘检测、阈值分割和单一分形维检测的结果,是一种非常有前途的方法。
This paper expatiates the notion of image fractal dimension and multi-scale fractal feature, proposes a ship target detection method based on multi-scale fraetal feature. Experimental results show that the difference of the multiscale fractal feature between artificial target and natural background is obvious. The proposed method can detect targets stable, is superior to the edge detection method, the threshold segment method and the single fractal dimension method, and is a promising detection method of the ship target.
