Query: A Structure Feature Algorithm for Multi-modal Forearm Registration   Augmented reality technology based on image registration is becoming
increasingly popular for the convenience of pre-surgery preparation and medical
education. This paper focuses on the registration of forearm images and digital
anatomical models. Due to the difference in texture features of forearm
multi-modal images, this paper proposes a forearm feature representation curve
(FFRC) based on structure compliant multi-modal image registration framework
(FAM) for the forearm.
