摘　　要：对颅颌面X片图像进行了研究。引入不变矩方法,讨论了将不变矩应用于颅颌面医学图像检索的可行性。实验结果表明:基于小波边缘检测的不变矩可有效地提取颅颌面的形状特征;采用欧式距离进行相似度测量,可有效检索出相似度较高的图片。检索的图片可以为疑似病例诊断提供帮助。This paper proposed a cranio-maxillo-facial image retrieval based content feature,introduced the proposal of the shape feature,and discussed the feasibility of moment invariants in image retrieval.Experiment results showed that invariant moments based on wavelet edge detection can extract the shape feature of the cranio-maxillo-facial effectively.With measure the similarity by euclidean distance,we can retrieve the image effectively.The retrieval image can help diagnose suspected cases.
