Computer reconstruction of 2-D photographs from alternative viewpoints
Neil D. Duffy · 1990
The reconstruction of mug-shots from various angles has obvious advantages where witnesses are attempting to identify a subject who may have been observed from a viewpoint other than that recorded on a frontal photograph. Alternatively, the ability to modify a frontal photograph in such a way that it allows reconciliation of the photograph and views of the subject as seen by witnesses from different viewpoints, has the potential to lead to a more accurate description of the subject being obtained. Both of these applications are facilitated by a computer graphics technique described, in which an image, held in computer memory, of a frontal facial photograph, is texture mapped onto the surface of an underlying 3D skeletal model.
