Abstract:
1. A computer-implemented method comprising: comparing in a processor content captured during a first session and represented in a model, and, content captured during a second session, different from the first session, and represented in one or more images, wherein comparing includes determining an offset between a representation of the model provided by an animation mesh and content of an image selected from the one or more images of the second session, wherein a surface feature of an object represented in the content of the first session corresponds to a different surface feature of an equivalent portion of the object represented in the content of the second session; substantially aligning the surface features to align the content of the first and second sessions by applying the offset to at least one of the model representing the first session content and the content of the selected image from the one or more images of the second session; combining the aligned content; and producing an updated version of the model by decomposing the combined content by computing principal components of the combined content and applying at least two or more weighting factors to the computed principal components, wherein the updated model is capable of representing content of the second session.
