Compiler based exploration of DSP energy savings by SIMD operations
— The growing use of digital signal processors (DSPs) in embedded systems necessitates the use of optimizing compilers supporting their special architecture features. Beside the ...

Estimation of mixtures of probabilistic pca with stochastic em for the 3d biplanar reconstruction of scoliotic rib cage
In this paper, we present a robust method for estimating the model parameters in a mixture of probabilistic principal component analyzers. This method is based on the Stochastic v...

Markerless 3D Face Tracking
We present a novel algorithm for the markerless tracking of deforming surfaces such as faces. We acquire a sequence of 3D scans along with color images at 40Hz. The data is then re...

Energy minimization with loop fusion and multi-functional-unit scheduling for multidimensional DSP
Energy saving is becoming one of the major design issues in processor architectures with multiple functional units (FUs). Nested loops are usually the most critical part in multim...
