Patent number: 10102347Abstract: The invention relates to a system for producing a representation of an object in image data, based on a template coupled to a model of the object, the system comprising a model unit for adapting the model to the object in the image data, and a template unit for adapting the template to the adapted model on the basis of the coupling between the template and the model. The template defines a representation of the object which is simpler to interpret than the model. Because the template of the invention is coupled to the model, the position, orientation and/or shape of the template is determined by the model adapted to the object in the image data. Hence, the template is adapted to the image data. The adapted template is capable of representing the object and its individual characteristics.Type: GrantFiled: September 17, 2009Date of Patent: October 16, 2018Assignee: Koninklijke Philips N.V.Inventors: Cristian Lorenz, Sebastian Peter Michael Dries, Steffen Renisch, Jens Von Berg
