|Zusammenfassung:||We describe a computational model of face recognition that makes use of the overlapping texture and shape information visible in different views of faces. The model operates on view dependent data from three-dimensional laser scans of human heads, wich provided three-dimensional surface data as well as surface image detail in form of a texture map. View-dependent information from the surface and texture representations was registered onto separate three-dimensional head models. We used an auto-associative memory model as a pattern completion device to fill in parts of the head from a lerned view when a test view with partially overlapping information was used as a memory key- We show that the overlapping visible regions of heads for both surface and texture data can support accurate recognition, even with pose differences of as much as 90 degrees (full face to profile view) between the learning and test view.|
