Name

vector_field_to_hom_mat2dT_vector_field_to_hom_mat2dVectorFieldToHomMat2dVectorFieldToHomMat2d — Approximate an affine map from a displacement vector field.

Signature

vector_field_to_hom_mat2d(VectorField : : : HomMat2D)

Description

vector_field_to_hom_mat2dvector_field_to_hom_mat2dVectorFieldToHomMat2dVectorFieldToHomMat2dVectorFieldToHomMat2d approximates an affine map from the displacement vector field VectorFieldVectorFieldVectorFieldVectorFieldvectorField. The affine map is returned in HomMat2DHomMat2DHomMat2DHomMat2DhomMat2D.

If the displacement vector field has been computed from the original image and the second image , the internally stored transformation matrix (see affine_trans_imageaffine_trans_imageAffineTransImageAffineTransImageAffineTransImage) contains a map that describes how to transform the first image to the second image . Note that the VectorFieldVectorFieldVectorFieldVectorFieldvectorField must be in relative coordinates as returned by optical_flow_mgoptical_flow_mgOpticalFlowMgOpticalFlowMgOpticalFlowMg.
