... of 3-D parameters from calibrated sets of 2-D parameters is computationally very efficient, requiring only a small fraction of computational power as compared to the low-level segmentation algorithms[5]. ... Motion Understanding the observation process is significantly non-trivial. Video images of the hu- man body are extremely high-dimensional signals and the mapping between body pose and...
