Signature

Description

vector_field_to_hom_mat2dvector_field_to_hom_mat2dvector_field_to_hom_mat2dVectorFieldToHomMat2dVectorFieldToHomMat2d 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 Iorig and the second image Ires, the internally stored transformation matrix (see affine_trans_imageaffine_trans_imageaffine_trans_imageAffineTransImageAffineTransImage) contains a map that describes how to transform the first image Iorig to the second image Ires. Note that the VectorFieldVectorFieldVectorFieldVectorFieldvectorField must be in relative coordinates as returned by optical_flow_mgoptical_flow_mgoptical_flow_mgOpticalFlowMgOpticalFlowMg.

Parallelization

• Multithreading type: reentrant (runs in parallel with non-exclusive operators).
• Multithreading scope: global (may be called from any thread).
• Processed without parallelization.
