“…We have taken into account different processor configurations in order to evaluate their impact on the runtime performance. The processing time includes the 3D-WT calculation (the wavelet transform part, up to 70%, is the most demanding part of the algorithm [15]), communication time, and I/O operations for a complete sequence decorrelation (64 frames). Figure 9 allows us to provide an absolute reference point of our experiments, in order to compare them with other experimental works.…”

“…They have not, however, considered the use of the GOF concept in order to minimize the memory requirements when computing the 3D-WT. In a recent study they have focused on the time taken by the wavelet transform decomposition making part of the JPEG 2000 and MPEG-4 VTC image compression standards [15]. They have used a shared memory programming paradigm based on OpenMP.…”

We introduce and evaluate the implementations of three parallel video-sequences decorrelation algorithms. The proposed algorithms are based on the nonalternating classic three-dimensional wavelet transform (3D-WT). The parallel implementations of the algorithms are developed and tested on a shared memory system, an SGI origin 3800 supercomputer making use of a messagepassing paradigm. We evaluate and analyze the performance of the implementations in terms of the response time and speed-up factor by varying the number of processors and various video coding parameters. The key points enabling the development of highly efficient implementations rely on the partitioning of the video sequences into groups of frames and a workload distribution strategy supplemented by the use of parallel I/O primitives, for better exploiting the inherent features of the application and computing platform. We also evaluate the effectiveness of our algorithms in terms of the first-order entropy.

In this paper, we introduce and evaluate the parallel implementations of two video sequences decorrelation algorithms having been developed based on the nonalternating three-dimensional wavelet transform (3D-WT) and the temporal-window method. The proposed algorithms have been proven to outperform the classic 3D-WT algorithm in terms of a better coding efficiency and lower computational requirements while enabling a lossless coding and a top-quality reconstruction: the two most highly relevant features to medical imaging applications. The parallel implementations of the algorithms are developed and tested on a shared memory system, a SGI Origin 3800 supercomputer, making use of a message-passing paradigm. We evaluate and analyze the performance of the implementations in terms of the response time and speed-up factor by varying the number of processors and various video coding parameters. The key point enabling the development of highly efficient implementations rely on a workload distribution strategy supplemented by the use of parallel I/O primitives, for better exploiting the inherent features of the application and computing platform. Two sets of I/O primitives are tested and evaluated: the ones provided by the C compiler and the ones belonging to the MPI/IO library.
