In this paper we propose an approach to recognize human actions using depth images. Here, we capture the motion dynamics of the object from the depth difference image and average depth image. The features from the space-time depth difference images are obtained from hierarchical division of the silhouette bounding box. We also make use of motion history(More)
With the advent of parallel processing architectures and a steep increase in parallelism found among the recent applications, GPGPUs have gained attention with respect to their importance in the execution of these applications. In this document, we specifically analyze Sparse-Matrix Vector Multiplication(SPMV) across different architectures, libraries and(More)
