1. A method for generating a 3-dimensional representation of a portion of an organism, comprising: collecting training data, wherein the training data includes a first set of training data and a second set of training data; building at least one statistical model having a set of parameters using the training data; comparing the at least one statistical model to a 2-dimensional image of the portion of the organism; modifying at least one parameter of the set of parameters of the statistical model based on the comparison of the at least one statistical model to the 2-dimensional image of the portion of the organism; passing the modified set of parameters representing the portion of the organism through the statistical model.
