In this paper we present an artificial immune system implemented on GPU (graphical processing unit) for visual applications. Immune response inspired algorithms need parallel processing and can efficiently exploit the computational power of GPUs. Performance evaluation shows that our implementation gives faster solution than previous methods. Experimental results are reported to demonstrate that the system […]

In this paper, we propose a system for the complete implementation of the advanced encryption standard (AES) for encryption and decryption of images and text on a graphics processing unit. The GPU acts as a valuable co-processor that relieves the load off the CPU. In the decryption stage, we use a novel technique to display […]

Based on GUI desktop environment, running PC-class applications with rich user experience has become popular in mobile devices. A window system is an essential component of GUI desktop. As a window system for mobile devices, we implemented X server on top of EGL and OpenVG. GPU-based X server described in this paper may serve as […]

The Compute Unified Device Architecture (CUDA) is a new programming platform making use of the unified shader design of the most current Graphics Processing Units (GPUs) from NVIDIA. In this paper, we apply this revolutionary new technology to implement the automatic time gain compensation (ATGC) for medical ultrasound imaging. The parallel box filtering method and […]

Muscle-based skin deformation could produce detailed visual quality. However, it always requires tedious labor work and the rendering speed is usually slow. In this paper, we propose a fast skin deformation method based on the common three-layer model, including skeleton, muscle and skin layer. First, Skeleton-driven smooth skinning technique is adopted to get the basic […]

The medical training systems based on virtual simulation are highly desired since minimally invasive surgical techniques have become popular to patients. The training system helps surgeon trainees to acquire, practice and evaluate their surgical skills, and the key component of such a system is to simulate the dynamic procedure such as 3D biological tissue deformation […]

The merging of multiple range images obtained by 3D measurement systems for generating a single polygon mesh, and processing for filling holes caused by unmeasured data or insufficient range images are essential processes for CAD, digital archiving of shapes, and CG rendering. Many of the existing processes that have been proposed for merging and interpolating […]

The Siggraph/Eurographics Graphics Hardware 2003 workshop, held in San Diego, will likely be remembered as a turning point in modern computing. In one of those rare moments when a new paradigm visibly begins changing general-purpose computing’s course, what has traditionally been a graphics-centric workshop shifted its attention to the nongraphics applications of the graphics processing […]

To overcome the limitations of triangle and point based surfaces several authors have recently investigated surface representations that are based on higher order primitives. Among these are MPU, SLIM surfaces, dynamic skin surfaces and higher order iso-surfaces. Up to now these representations were not suitable for interactive applications because of the lack of an efficient […]

The aim of this paper is the efficient use of CPU and GPU clusters for a general path-dependent exotic European pricing, and their comparison in terms of speed and energy consumption. To reach our goal, we propose a parallel random number generator which is well suited to the parallelization paradigm, then, we implement a multidimensional […]

Ant Colony Optimization is computationally expensive when it comes to complex problems. The Jacket toolbox allows implementation of MATLAB programs in Graphics Processing Unit (GPU). This paper presents and implements a parallel MAX-MIN Ant System (MMAS) based on a GPU+CPU hardware platform under the MATLAB environment with Jacket toolbox to solve Traveling Salesman Problem (TSP). […]

The history of humanity is that we strive to use better tools and knowledge to build even better tools, and extend further the border of knowledge. In the past 50 years, CPU, as a dominant paradigm for computing, has provided exponential growth as predicted by Moore’s Law with remarkable accuracy. We have been leveraging CPUs […]
