摘要
为实现有变形X射线图像的有效识别,对有变形图像不变矩进行理论推导,并针对变形情况提出了3个新的改进不变矩。将原不变矩和新提出的改进不变矩应用于不同图像,分析并验证所构建改进不变矩的有效性,并提出基于改进不变矩的变形X射线图像识别方法。实验结果表明,提出的改进不变矩具备有变形情况下的尺度、旋转、平移不变性,所提出的基于改进不变矩的变形X射线图像识别方法能够有效提高识别准确率,效果更佳。
In order to realize the effective recognition of distorted X-ray images,the moment invariants of distorted images are deduced theoretically.Three new improved moment invariants are proposed for distortion.The original moment invariants and the new improved moment invariants proposed in this paper are inputted to different images to study and verify the effectiveness.The distorted X-ray image recognition method based on improved moment invariants is proposed.The experimental results show that the new improved moment invariants proposed in this paper has the invariance of scale,rotation and translation in the case of distortion.The proposed distorted X-ray image recognition method based on improved moment invariants can raise accuracy and achieve better effectiveness.
