The matching problem is formulated as an approximate controllability problem involving a cost functional whose gradient is computed using an adjoint equation based methodology. The time discrete version of the image matching problem is also discussed in this work.engjournal articlehttp://www.sciencedirect.com/science/article/pii/S0893965907002807http://www.sciencedirect.comrestricted access515.16Shape identificationImage matchingGroup of diffeomorphismsControllabilityAdjoint equationTime discrete controllabilityGeometria algebraica1201.01 Geometría Algebraica
