| 摘 要： | 针对区域矩需要计算全图像素的统计分布、计算量大的问题,构造了基于目标形状的仿射不变轮廓矩。首先采用PDE方法推导得到了6个仿射不变矩的数学模型,然后将积分区间变为目标区域的边界,计算得到基于目标形状的仿射不变轮廓矩,最后通过三类舰船不同姿态下的图像进行了实验验证并对其稳定性进行了分析。研究结果表明:仿射不变轮廓矩具有较好的稳健性及区分度,可将其作为不变特征用于舰船目标识别。

| Abstract: | Region moments needs to compute the statistical distribution of all the image pixels with the large amount of calculation. In order to solve these problems,affine invariant contour moments are constructed which are based on the shape of the object. Firstly,six mathematical models of affine invariant moments are obtained by the method of PDE. Then the interval of integration is changed into the object’s boundary and affine invariant contour moments are calculated. Finally,experiments are verified through the images of three types of ship under different attitudes and the stability analysis is proceeded. Results indicate that affine invariant contour moments have good robustness and discrimination,and they can be used as invariant features for ship target recognition. |
