Modern forensic facial reconstruction techniques are based on an understanding of skeletal variation and tissue depths. These techniques rely upon a skilled practitioner interpreting limited data. To (i) increase the amount of data available and (ii) lessen the subjective interpretation, we use medical imaging and statistical techniques. We introduce a(More)
In this paper a dynamic programming algorithm for simultaneous speech segmentation and phoneme recognition is presented. Given a sequence of samples of an unknown speech pattern and a library of phonemes, this algorithm finds the best phonological match and, with a backtracking step, identifies the phoneme boundaries. This approach is different from a(More)
Interactive deformable object modeling is important for a number of application areas. Unfortunately, computational complexity quickly grows beyond the capabilities of consumer systems as model detail increases. Our first contribution is to analyze this application, and present details that might aid in optimizing existing algorithms or in developing new(More)
Physical modeling of a mass-spring system allows for realistic object motion and deformation in a virtual environment. Previous work in this type of physical modeling relies on general-purpose hardware, and cannot offer the performance necessary for realtime human-machine interaction. In this paper, we consider the co-design of software and hardware in(More)
