Description

vector_field_to_hom_mat2dVectorFieldToHomMat2d approximates an affine map from the displacement vector field VectorFieldvectorFieldvector_field. The affine map is returned in HomMat2DhomMat2Dhom_mat_2d.

If the displacement vector field has been computed from the original image \(I_{\mbox{orig}}\) and the second image \(I_{\mbox{res}}\), the internally stored transformation matrix (see affine_trans_imageAffineTransImage) contains a map that describes how to transform the first image \(I_{\mbox{orig}}\) to the second image \(I_{\mbox{res}}\). Note that the VectorFieldvectorFieldvector_field must be in relative coordinates as returned by optical_flow_mgOpticalFlowMg.
