Question

如何在opencv python3中使用薄板样条曲线将图像从一种形状转换为另一种形状。在c ++中我们有形状变换器类。在opencv python3中我们如何实现它。

Answer 1

在python3中确实存在opencv的薄板样条。您可以使用帮助功能获取有关哪些功能存在以及如何使用它们的更多信息：

Help on ThinPlateSplineShapeTransformer object:

class ThinPlateSplineShapeTransformer(ShapeTransformer)
|  Method resolution order:
|      ThinPlateSplineShapeTransformer
|      ShapeTransformer
|      Algorithm
|      builtins.object

|  __new__(*args, **kwargs) from builtins.type
|      Create and return a new object.  See help(type) for accurate 
signature.

|  __repr__(self, /)
|      Return repr(self).
