对功能的空间坐标进行翘曲操作。它用于根据由一组控制向量定义的空间变换来调整一组观察到的输入特征。This transformer computes an affine (scale, rotation, and offset) transformation based on控制矢量特征并将这种转变应用于观测到的features to generate output, and produces good corrections when the entire set of观测到的data requires a single transformation.
每控制feature represents a control vector whose start point is at some location in the original观测到的data space, and whose end point is at the corresponding location in the desired output data space. The control vector represents the correction required to go from the observed vertex to the desired vertex. (Control vectors with only one point are interpreted as a requirement that this location not change from the observed dataset to the reference dataset. This is often referred to as a tie point.)
输入端口
必须将两组功能路由到此变压器中。
控制
输入的功能控制port represent the control features used to compute the corrections.
观测到的
输入的功能观测到的port are the features that will be corrected.
Output Ports
Corrected
The modified观测到的features are output via theCorrectedport.
Parameters
Not applicable.
- The橡胶鹰变换器提供类似的功能，但对每个功能应用不同的转换观测到的vertex, depending on its distance to nearby控制vectors。这使得这使得橡胶鹰more appropriate for cases when the distortions in the data are not constant.
- 还请看看Affiner., which performs an affine transformation on the coordinates of the feature.
