1. A method for three-dimensional (3D) anatomical modeling, the method comprising:
co-registering one or more obtained two-dimensional (2D) images based on a common coordinate system, wherein the 2D images are associated with bony anatomy of a patient;
identifying a first historical 3D bone model corresponding to a first candidate bone based on bone properties of the bony anatomy and contextual information including at least demographic information associated with the patient;
repositioning one or more of the 2D images superimposed on the first historical 3D bone model to substantially align the one or more of the 2D images with the first historical 3D bone model;
modifying one or more surface regions of a second historical 3D bone model that corresponds to a second candidate bone and is identified based on the repositioning;
comparing the first or second sets of candidate bones to the 2D images collectively or as open shell surfaces;
selecting one or more bony surfaces represented by visible portions of the bony anatomy of the patient or a shape of the bony anatomy of the patient; and
generating a 3D model from the modified second historical 3D bone model, wherein the generated 3D model corresponds to the bony anatomy.
 
15. A method for three-dimensional (3D) anatomical modeling, the method comprising:
co-registering one or more obtained two-dimensional (2D) images based on a common coordinate system, wherein the 2D images are associated with bony anatomy of a patient;
identifying a first historical 3D bone model corresponding to a first candidate bone based on bone properties of the bony anatomy and contextual information including at least demographic information associated with the patient;
repositioning one or more of the 2D images superimposed on the first historical 3D bone model to substantially align the one or more of the 2D images with the first historical 3D bone model;
modifying one or more surface regions of a second historical 3D bone model that corresponds to a second candidate bone and is identified based on the repositioning;
identifying a plurality of historical 3D bone models corresponding to a plurality of candidate bones based on the bone properties of the bony anatomy and the contextual information, wherein the bony anatomy comprises a joint comprising multiple bones and one or more of the candidate bones are associated with different patients; and
generating a 3D model from the modified second historical 3D bone model, wherein the generated 3D model corresponds to the bony anatomy.
 
27. A method for three-dimensional (3D) anatomical modeling, the method comprising:
co-registering one or more obtained two-dimensional (2D) images based on a common coordinate system, wherein the 2D images are associated with bony anatomy of a patient;
identifying a first historical 3D bone model corresponding to a first candidate bone based on bone properties of the bony anatomy and contextual information including at least demographic information associated with the patient;
repositioning one or more of the 2D images superimposed on the first historical 3D bone model to substantially align the one or more of the 2D images with the first historical 3D bone model;
modifying one or more surface regions of a second historical 3D bone model that corresponds to a second candidate bone and is identified based on the repositioning;
repeating the repositioning for the second historical 3D bone model, without modifying the surface regions;
identifying a third historical 3D bone model based on the repositioning of the second historical 3D bone model, when the second historical 3D bone model fails to satisfy a threshold accuracy; and
generating a 3D model from the modified second historical 3D bone model, wherein the generated 3D model corresponds to the bony anatomy.
 
39. A method for three-dimensional (3D) anatomical modeling, the method comprising:
co-registering one or more obtained two-dimensional (2D) images based on a common coordinate system, wherein the 2D images are associated with bony anatomy of a patient;
identifying a first historical 3D bone model corresponding to a first candidate bone based on bone properties of the bony anatomy and contextual information including at least demographic information associated with the patient;
repositioning one or more of the 2D images superimposed on the first historical 3D bone model to substantially align the one or more of the 2D images with the first historical 3D bone model;
modifying one or more surface regions of a second historical 3D bone model that corresponds to a second candidate bone and is identified based on the repositioning;
identifying the second historical 3D bone model based on a comparison of one or more portions of the bony anatomy, in one or more of the 2D images, with a 2D representation of the first historical 3D model following the repositioning, wherein the one or more portions are of a silhouette of the bony anatomy and the comparison resolves one or more ambiguous bone film projections; and
generating a 3D model from the modified second historical 3D bone model, wherein the generated 3D model corresponds to the bony anatomy.
