simplicial map

There are geometrical deformations,named plane homography,between corresponding feature windows on different images of the same patch on scene surface.

不同视点图像中相应特征点邻域窗口之间存在几何上的透视畸变,这可用平面单应映射来表示,而目前大多匹配算法将该映射用仿射变换模型来近似,即用具有仿射不变性的特征进行图像的匹配。

There are geometrical deformations between corresponding feature windows on different images of the same scene sur- face,which can be represented by a homography on 2D plane.

不同视点图像中相应特征点邻域窗口之间存在几何上的透视畸变,这可以用平面单应映射来表示,而目前大多特征匹配算法将该映射用仿射变换模型来近似,即用具有仿射不变性的特征进行图像的匹配。

The homography between corresponding matching windows can be approximated by an affine model.

两幅图像中相应特征点邻域窗口之间的单应映射可以用仿射变换模型来近似。
