In this paper, we present Compute Unified Device Architecture i.e. CUDA based pyramidal image blending algorithm using an object oriented design patterns. This algorithm is an essential part of an image stitching process for a seamless panoramic mosaic. The CUDA framework is a novel GPU programming framework from NVIDIA. We introduce an object oriented(More)
In this paper, we propose and implement an object oriented framework for the GPU based image processing. Compute Unified Device Architecture i.e. the CUDA is a novel and promising GPU programming framework from the NVIDIA. The CUDA has been used to speedup many computationally intensive graphics as well as non graphics applications, but it requires more(More)
A visualization of large datasets requires ultra high resolution. Data wall systems provide large number of pixels by combining a power of multiple graphics cards. In this paper, we propose and realize an object oriented framework for the Message Passing Interface based parallel rendering. We introduce a GUI based viewer called the TiledRenderer, which is(More)
High resolution displays utilizing an array of commodity projectors are becoming popular approach(also called tiled displays) for visualizing high resolution content like scientific data-sets. These systems provide a relatively cheaper and flexible alternative to displays based on single high resolution monitor or projector. This approach inherently(More)
Robots are deployed to perform repeatable as well as hazardous tasks because of their inherent safety, reliability, consistency and accuracy. Recently robots are manipulated remotely using the binocular stereo vision. In this paper, we propose and implement a real-time stereoscopic viewer for telerobotics using open source software. We manipulate the KUKA(More)
Image stitching algorithms combine multiple low resolution images and provide a single high resolution composite image with a larger field of view available for video surveillance. In this research work, we put forward and realize real-time panorama composition for a video surveillance application using the power of a GPU. We utilize a cross platform OpenGL(More)
This paper presents heuristic algorithms that may be used for light-path routing and wavelength assignment in optical WDM networks under dynamically varying traf®c conditions. We consider both the situations where the wavelength continuity constraint is enforced or not enforced along a light-path. The performance of these algorithms has been studied through(More)
In this work, we manipulate an industrial robot from a remote place through a Local Area Network using a force feedback enabled Phantom haptic device as a master, and a stereo vision system for viewing as well as for depth estimation. We propose and implement a stereo vision guided telerobotics system for autonomous pick and place operations. The robot gets(More)
Stereo vision systems are essential for the 3D object reconstruction, industrial automation, telerobotics and many more. Stereo rectification process aligns the left and the right images such that their respective image rows are accurately aligned with each other. In this paper, we propose and implement a real-time stereo rectification of the high(More)
In this research work, we propose and realize a real-time stereoscopic vision system for neurosurgery training using a surgical stereoscopic microscope. We connect a pair of high resolution IP cameras to a surgical microscope through a dual port microscope beam splitter and a pair of microscope video adaptors. We make use of the specifically designed(More)
