An implantable device for use in tissue and ligament repair comprising at least one knitted section and at least one single continuous fiber traversing the at least one knitted section, the at least one single continuous fiber forming a plurality of traverses extending through the at least one knitted section. The implantable device may comprise at least one single continuous silk fiber. The implantable device is suitable for use in a variety or reconstructive or support applications such as breast reconstruction, mastopexy, breast augmentation revision, breast augmentation support, standard breast augmentation, chest wall repair, organ support, body contouring, abdominoplasty, facial reconstruction, hernia repair, and pelvic floor repair.

Pre-surgical planning for cranial and facial reconstruction includes preparing a computer generated jaw or skull model for determining a locational position for a dental implant, a surgical bone implant to repair missing bone in the cranium, install ear prostheses, and / or install nose prostheses. The computer generated jaw or skull model is made from medical imagery and computer aided design. A surgical guide is prepared with oversize holes in registration with analogs for the dental or surgical bone implants to be inserted at the locational positions determined by a dentist or surgeon in the jaw or cranial skull model. The surgical guide is fitted atop each analog, and the surgical guide is bonded to the jaw or skull model at a predetermined angle of the analog in the jaw or skull. The surgical guide is removed from the model attached to the law or skull of a patient for accurate drilling during the dental or surgical procedure for insertion of the implants into the jaw or skull of the patient.

The invention is a three-dimensional face reconstruction method, which automatically reconstructs a three-dimensional face model from a single frontal face image, and proposes two schemes, the first one: offline generation of a human face deformation model; automatic detection of people in the input image by using Adaboost Face location; automatically locate keypoints on the face in the input image using an active appearance model; reconstruct the geometry of the 3D face based on the shape components of the face deformation model and the face keypoints on the image; use shape-independent texture as the target Image, use the texture component of the face deformation model to fit the face texture to obtain the complete face texture; get the reconstruction result after texture mapping. The difference between the second type and the first type is that after reconstructing the geometric shape of the 3D face, the face texture fitting is not performed, but the input image is directly used as the texture image to obtain the reconstruction result. Solution 1 of the present invention is suitable for application in the fields of film and television production, three-dimensional face recognition, etc., and solution 2 has a fast reconstruction speed.

A computer-implemented method for generating a three-dimensional model of an object. The method includes generating a coarse geometry mesh of the object; calculating an optimization for the coarse geometry mesh based on photometric consistency and surface consistency associated with the coarse geometry mesh; and refining the coarse geometry mesh with the optimization to generate the three-dimensional model for the object.

The present invention provides a functionally graded bioactive glass / ceramic composite structure or bioactive glass / ceramic / bioactive glass sandwich structure for use in such applications as damage resistant, ceramic dental implants, immediate tooth replacement, endodontic posts, orthopedic prostheses, orthopedic stems, bone substitutes, bone screws, plates, and anchors, nonunion defects repair, alveolar ridge augmentation, missing small bone parts (e.g. fingers, toes, etc), maxilla facial reconstruction, spinal fusion, and scaffolds for bone regeneration, comprising a residual bioactive glass or glass-ceramic layer at all accessible surfaces, followed by an underlying graded glass-ceramic layer, and then an dense interior ceramic. Further, the invention provides methods for making the same structure.

The invention discloses a high-fidelity face three-dimensional reconstruction method based on a multilevel deformation model. According to the method, a video image sequence is used as input data, camera parameters and camera loci are restored through detection and tracking of light stream feature points, extraction and matching of face feature points as well as camera calibration by utilizing a movement restoration structure technology, a face multilevel deformation model is proposed, and then a high-fidelity face three-dimensional model of a target face is obtained by texture mapping. According to the method, the face multilevel deformation model is proposed by combining the deformation model technology with the movement restoration structure technology, so that the reconstruction result highly similar to the target face can be achieved; meanwhile, the defect of surface noise appearing in the traditional movement restoration structure is overcome, and face details can be provided by utilizing the movement restoration structure; and the high-fidelity face model obtained by the reconstruction method is widely applied in the fields of face recognition, personalized customized games, virtual reality, security department and the like.
