| 摘 要： | 为了解决传统方法构造的矩不变量特征集存在的完备性和独立性问题,提出了一种完备的伪Zemike矩相似变换(旋转、平移和缩放)不变量集的构造方法,并给出了系统的推导和证明.首先推导了几何变换前后图像的伪Zemike矩之间的关系,然后基于该关系得到了伪Zernike矩的相似不变量集,并将其表示成变换前图像的同阶和低阶伪Zer...

| Abstract: | To resolve the completeness and independence of an invariant set derived by the traditional method, a systematic method for deriving a complete set of pseudo-Zernike moment similarity (translation, scale and rotation) invariants is described. First, the relationship between pseudo-Zernike moments of the original image and those of the image having the same shape but distinct orientation and scale is established. Based on this relationship, a complete set of similarity invariants can be expressed as a linear... |
