Firstly, affine covariant neighborhoods of visual words are used to verify the spatial consistency. Secondly, a set of affine transformation matrices between the corresponding covariant regions is calculated, and the matrix with the most inliers is chosen as the best matching affine transformation matrix. In this step, only a single pair of corresponding affine covariant regions is used to calculate the 6 degree of freedom affine transformation for acceleration. In the last step, the spatial consistency is verified by the BMATM.

首先通过视觉关键词仿射协变的空间邻近特征集进行初步空间关系一致性匹配；然后计算对应仿射协变区块的多组可能的仿射变换矩阵，并选择满足区块匹配最多的变换矩阵作为对象与图像之间最终仿射变换矩阵，其中，仅利用一对协变区块来计算自由度为6的仿射变换的算法有效地提高了计算速度和鲁棒性；最后通过计算出的仿射变换矩阵来精确验证对象与图像之间的空间位置关系是否一致。

This paper integrates linear affine transformation and nonlinear affine transforma-tion"s approach ability. Integrated affine transformation not only inherits the linear affine transformation"s low bit rate merit,but also inherits the nonlinear affine transformations approach ability.The method proposed in this paper is a new method, and never be proposed in other papers.

affine transformation：仿射变换

仿射变换(Affine Transformation)和图象卷绕(Image Warping)是两类常见的几何运算. 前者属于射影几何变换,多用于图象配准(Image Registration)作为比较或匹配的预处理过程;后者用控制点及插值过程来定义,将一幅图象逐渐变化到另一幅图象的图象变形(Morphing)过程是其典型的应用,

affine transformation：仿射转换

一,转换方式介绍 : 六参数仿射转换(Affine transformation) 影像坐标系统与框标座标系统为两平面之间的转换,由於框标座标是右旋座标系统,而影像座标却是左旋的座标系,若采用六参数正形转换时,在同一个比例尺参数下无法进行转换,故采用六...
