Real-time arbitrary view rendering on GPU from stereo video and time-of-flight camera

Generating in-between images from multiple views of a scene is a crucial task for both computer vision and computer graphics fields. Photorealistic rendering, 3DTV and robot navigation are some of many applications which benefit from arbitrary view synthesis, if it is achieved in real-time. GPUs excel in achieving high computation power by processing arrays of […]

Rapid star map simulation based on GPU

Proposed and implemented a rapid star map simulation method based on GPU. The method used the vertex shaders of OpenGL shading language to perform real-time calculation of star positions. Combined with the display list technology, the results of calculation were used to perform the simulation of the initial star maps, then the initial star maps […]

Fast implementation of fully iterative scatter corrected OSEM for HRRT using GPU

Accurate scatter correction is especially important for high-resolution 3D PETs due to the lack of inter-slice septa. To address this problem, a fully 3D iterative scatter-corrected OSEM in which a 3D single scatter simulation (SSS) is alternatively performed with a 3D OSEM reconstruction until convergence was recently proposed. However, due to the computational complexity of […]

LOD Terrain Rendering by Local Parallel Processing on GPU

In this paper, we present a new technique for highly efficient terrain rendering using continuous view-dependent Level-of-Detail based on hardware tessellation unit found in modern GPUs. Our technique is based on parallel local processing, in the sense that the results at each terrain patch do not depend on results already obtained at other patches. This […]

Case study: Runtime reduction of a buffer insertion algorithm using GPU parallel programming

In this paper, we present a case study on runtime reduction of VLSI CAD programs using parallel computing. Specifically, we parallelize a buffer insertion algorithm that minimizes power dissipation. We choose Graphic Processing Units (GPUs) as the low-cost hardware that supports parallel computing. We redesign the algorithm data structure to accommodate GPU based computing. As […]

GCS: High-Performance Gate-Level Simulation with GP-GPUs

In recent years, the verification of digital designs has become one of the most challenging, time consuming and critical tasks in the entire hardware development process. Within this area, the vast majority of the verification effort in industry relies on logic simulation tools. However, logic simulators deliver limited performance when faced with vastly complex modern […]

GPU-accelerated fault simulation and its new applications

GPUs have recently been explored as a new general-purpose computing platform, which are suitable for the acceleration of compute-intensive EDA applications. In this paper we describe a GPU-based one- to n-detection fault simulator for both stuck-at and transition faults, which demonstrates a 20X speedup over a commercial CPU-based fault simulator. We further show new fault-simulation-based […]

GPU Implementation of the LFT Shape Matching Algorithm

Registration of partial scan data sets is still a challenge for today’s CAD systems and CAD system users. Many of the known methods rely on user interaction or feature recognition. For non-regular users this is too time consuming and error prone. The paper describes a method to register partial scan data by fitting a large […]

Analysis of periodic structures with GPU accelerating

Various FDTD approaches has been applied in the analysis of periodic structures, among which Spectral FDTD is a straight-forward and robust one. This essay proposed an improved Spectral FDTD algorithm that improves the simulation speed of off-normal incident case without jeopardizing accuracy. Together with GPU accelerating, as is proven by the example, the proposed acceleration […]

GPU accelerated high intensity ultrasound acoustical power computation

The simulation of the hepatocellular carcinoma therapy effects is often used for the intervention planning. As the physical-based model of the simulation is very time-consuming, the speed of this method becomes an obstacle during the clinical application simulation. In order to accelerate the simulation, a GPU-based (Graphic Processing Unit) acceleration method of the pressure field […]

Optimized GPU histograms for multi-modal registration

GPU-based systems are used more and more for medical image processing because of their parallel processing power and memory bandwidth. Impressive results have been achieved when registering large volume, however, one of themost-used similarity measures for multi-modal registration – mutual information – is not well suited for the streaming architecture because of its memory access […]
