Realistic objects simulation is important in visual reality and its performance is impacted by physical shape computation. Due to fast development and robust programmability of graphics hardware recently, much research takes advantage of GPU (Graphics Processing Unit) computation to accelerate simulations in virtual environment. This paper presents painting style synthesis that fully simulates image behaviors […]

This paper describes a method to correct the distortions in the images captured by a stereo video camera rig. We developed a code which can be implemented both on CPUs and GPUs which are used respectively to process still images or videos. The processing scheme is centered on the pre-calculation of a deformation texture, based […]

The aim of this paper is to show that a special kind of boundary value problem for second-order ordinary differential equations which reduces to the problem of solving a tridiagonal system of linear equations with almost Toeplitz structure can be efficiently solved on modern heterogeneous computer architectures based on CPU and GPU processors using an […]

In recent years, considerable research has been devoted to the efficient representation, modeling, processing and rendering of point-based models (point clouds). Due to their conceptual simplicity and superior flexibility, point-based representations evolved into a valuable alternative to polygonal meshes. This paper explores the problem of extracting direct visibility from point clouds without explicitly reconstructing the […]

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 […]
