Aerial surveillance missions require a geographical region known as the area of interest to be inspected. The route that the aerial reconnaissance vehicle will follow is known as the flight route. Flight route planning operation has to be done before the actual mission is executed. A flight route may consist of hundreds of predefined geographical […]

The approach used to calculate the two-electron integral by many electronic structure packages including generalized atomic and molecular electronic structure system-UK has been designed for CPU-based compute units. We redesigned the two-electron compute algorithm for acceleration on a graphical processing unit (GPU). We report the acceleration strategy and illustrate it on the (ss|ss) type integrals. […]

The exposure of high dynamic range scenes needs special attention to capture all details. A new method for a low dynamic monitoring preview of the local scene details is presented. We follow the idea of edge preserving nonlinear bilateral filtering instead of classic methods such as linear high pass filtering or histogram equalization. Real-time performance […]

Bio-inspired computer vision is an emerging field. It aims to reproduce the capabilities of biological vision systems, eventually to simulate the visual functions for various purposes. In this paper, we propose a bio-inspired computer visual system using Graphical Processing Unit (GPU), and its application on breast cancer prognosis. The system extracts visual features from an […]

The plant leaf modeling and rendering is one of the most challenging problem in virtual botany due to its complex morphological and optical characteristics. In this paper, we present a method of realistic leaf modeling and rendering. We extract the leaf outline and venation by using the algorithm of leaf image edge detection. The leaf […]

Parallel computing becomes more and more popular and the scale of software improves accordingly. A large application is made up of many small tasks. Some statistics indicate that some tasks of 80% software can support parallel execution. The difficulties are how to decompose one application into many tasks and exploit the parallelization among these tasks. […]

Imaging systems for computer vision play an important role in today’s world. Typical computer vision systems operate on large scale scenes, where objects are relatively far from the camera and the depth of field in which objects appear focussed is large. Close-range camera systems, on the other hand, typically have a narrow depth of field. […]

Real-time haptic rendering of three-dimensional fluid flow will improve the interactivity and realism of applications ranging from video games to surgical simulators, but it remains a challenging undertaking due to its high computational cost. Humans are very familiar with the look and feel of real fluids, so successful interactive simulations need to obey the mathematical […]

For scientific management for coal in coal-fired power plant, statistic for coal storage at a coal yard is necessary. A measurement method for coal pile volume on basis of Graphic Process Unit introduced in this article is to make use of a laser telemeter to collect three dimensional coordinate data on several surface point of […]

General purpose programming on the graphics processing units(GPGPU) has received a lot of attention in the parallel computing community as it promises to offer a large computational power at a very low price. GPGPU is best suited for regular data parallel algorithms. They are not directly amenable for algorithms which have irregular data access patterns […]

This paper presents a 2-D/3-D registration method for the alignment of cardiac X-ray images to ECG gated CTA data of the coronary arteries. The purpose of our work is to provide visualization of instruments in relation to pre-operative CTA data during interventional cardiology for improved image guidance, especially in complex procedures. The method utilizes the […]
