Solving linear equations is a common problem in the fields of science and engineering. Accelerating its solving process is of great significance. Modern GPUs are high performance many-core processors fit for large scale parallel computing. They provide us a novel way for accelerating the solving process. A GPU based parallel Jacobi’s iterative solver for dense […]

Point sampled geometry has recently gained significant interest due to the tremendous advances in the technology of 3D scanning and the representational simplicity afforded by avoiding any need for explicit connectivity information. Their use in creating highquality rendered images is however still limited. Till date, most renderings of point sampled surfaces use the Phong illumination […]

Molecular dynamics simulations of proteins play a growing role in various fields such as pharmaceutical, biochemical and medical research. Accordingly, the need for high quality visualization of these protein systems raises. Highly interactive visualization techniques are especially needed for the analysis of time-dependent molecular simulations. Beside various other molecular representations the surface representations are of […]

Option pricing is an important problem in computational finance due to the fast-growing market and increasing complexity of options. For option pricing, a model is required to describe the price process of the underlying asset. The GARCH model is one of the prominent option pricing models since it can model stochastic volatility of the underlying […]

Current trends in digital display technology show a marked interest towards 3D displays, which allow three dimensional images to be conveyed to viewers. Among various 3D display techniques, auto stereoscopic display appears to be promising due to the use of optical trickery at the display, allowing glass-free viewing. However, the cost of generating and transmitting […]

The main purpose of this paper is to demonstrate how we make use of the powerful graphics processor, NVIDIA GTX280, in numerical simulation with the support of double precision floating number. Apply the finite volume method in simulating the Euler equation, two well-known examples for travelling shock waves were examined in high resolution. We had […]

The paper proposes a real-time subsurface scattering rendering method for dynamic objects. Subsurface scattering owned by translucent objects is a complex optical phenomenon. Since the complexity of the property description of translucent materials and their interaction with light, the pre-computing methods are usually used to render subsurface scattering of translucent objects, but these approaches either […]

An airborne demonstrator for real-time hyperspectral target detection has been developed at FFI. The real-time image processing is challenging, not only due to the computational complexity of the algorithms, but also due to the sustained high data rate. A software framework has been designed in C++ to handle large data flows in a nonlinear pipeline […]

Omnidirectional videos are usually mapped to planar domain for encoding with off-the-shelf video compression standards. However, existing work typically neglects the effect of the sphere-to-plane mapping. In this paper, we show that by carefully designing the mapping, we can improve the visual quality, stability and compression efficiency of encoding omnidirectional videos. Here we propose a […]

Graphics Processing Units (GPUs) are increasingly used to solve non-graphical scientific problems. However, it has been shown that the reliability of the GPUs is a concern because of the occurrence of the soft and hard errors. The checkpoint/restart is the most commonly used technique to achieve fault tolerance in the presence of failures. This work […]

Histology is the study of the structure of biological tissue using microscopy techniques. As digital imaging technology advances, high resolution microscopy of large tissue volumes is becoming feasible; however, new interactive tools are needed to explore and analyze the enormous datasets. In this paper we present a visualization framework that specifically targets interactive examination of […]

The introduction of General-Purpose computation on GPUs (GPGPUs) has changed the landscape for the future of parallel computing. At the core of this phenomenon are massively multithreaded, data-parallel architectures possessing impressive acceleration ratings, offering low-cost supercomputing together with attractive power budgets. Even given the numerous benefits provided by GPGPUs, there remain a number of barriers […]
