Signature

Description

vector_field_to_hom_mat2dvector_field_to_hom_mat2dVectorFieldToHomMat2dVectorFieldToHomMat2dvector_field_to_hom_mat2d approximates an affine map from the displacement vector field VectorFieldVectorFieldVectorFieldvectorFieldvector_field. The affine map is returned in HomMat2DHomMat2DHomMat2DhomMat2Dhom_mat_2d.

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_imageAffineTransImageAffineTransImageaffine_trans_image) contains a map that describes how to transform the first image to the second image . Note that the VectorFieldVectorFieldVectorFieldvectorFieldvector_field must be in relative coordinates as returned by optical_flow_mgoptical_flow_mgOpticalFlowMgOpticalFlowMgoptical_flow_mg.

Execution Information

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