VComposable¶
- class menpo.transform.base.composable.VComposable[source]¶
Bases: object
Mix-in for Vectorizable ComposableTransform s.
Use this mix-in with ComposableTransform if the ComposableTransform in question is Vectorizable as this adds from_vector() variants to the ComposableTransform interface. These can be tuned for performance.
- compose_after_from_vector_inplace(vector)[source]¶
Specialised inplace composition with a vector. This should be overridden to provide specific cases of composition whereby the current state of the transform can be derived purely from the provided vector.
Parameters: vector : (n_parameters,) ndarray
Vector to update the transform state with.
