| 摘 要： | 研究了图像边界矩的模糊不变性,推导出模糊边缘带区域不变矩中准(2Fe)～准(7Fe)与该图像所对应的清晰图像的边界不变矩准2～准7一致的结论。利用该结论,对模糊图像提取边界不变矩特征时,可不必首先精确提取其精确边缘,方便了边界不变矩特征的提取,提高了边界不变矩特征提取的鲁棒性。仿真实验结果也验证了结论的正确性。

| Abstract: | The paper studies the blurred invariability of image boundary moment and deduces a conclusion that blurred edge area moment invariance Φ2(Fe) ~Φ7(Fe) are consistent with the corresponding clean image’s edge moment invariance Φ2~Φ7.Using this result，it is not necessary to precisely extract its crisp edge at first when extracting boundary invariable moment from blurred images.This makes it convenient to extract boundary invariable moment features and promotes the robustness of boundary invariable moment feature extracting.Experimental results also validate the correctness of the conclusion. |
