Nonlinear Image Processing, 1992. The data represented four male and four female faces. Adequate feature detection was achieved for 100 of these faces. 97 recognition accuracy was reported for the individual features and 100 for the whole face.
Humans have a remarkable ability to recognize faces from sketches.
Nonlinear Image Processing, 1992. The immediate disadvantage of such systems is the increased complexity of the equipment needed to acquire the information. In the first two cases the surface data is transformed into curvature maps, whereas the work of Chang, et al. On the basis of the previous discussion of potential systems, it was decided to attempt a realistically practical system based on the use of three dimensional information. Gaile G.
