Computer vision methods for fragmented skull prototyping: Bio-CAD application

In biomedical domain, human skull fractures caused by accidents or any other reasons are required to reassemble. The process of reassembling the fragmented skulls is called skull prototyping or skull completion, followed by the skull repairing process. In the human body, skulls are the regions that are fragmented along a wide range of geometric information that may be fragile. Resolved skull has been supposed to possess higher conformity, particularly under the area of frontal facial along the subtle substrate. With the development of the computer-aided design (CAD) tool, it is possible to complete the fragmented skulls and/or repair damaged skulls using the various computer vision techniques. The bio-CAD methods are introduced for fragmented skull completion and/or damaged skull repairing. This paper has presented a study of various skull prototyping methods. The main focus of this study is to review the computer vision techniques used for human skull prototyping. A systematic study of the state of methods and their comparative analysis is presented in this paper. The automatic skull completion and/or repairing identified as the critical challenge and requirement according to the reviewed literature.
