tailieunhanh - GpuCV: An OpenSource GPU-Accelerated Framework for Image Processing and Computer Vision Yannick Allusse

This paper presents GpuCV, an open source multi-platform library for easily developing GPU-accelerated image processing and Computer Vision operators and applications. It is meant for computer vision scientist not familiar with GPU technologies. It is designed to be compatible with Intel’s OpenCV library by offering GPU-accelerated operators that can be integrated into native OpenCV applications. | GpuCV An OpenSource GPU-Accelerated Framework for Image Processing and Computer Vision Yannick Allusse EPH Telecom Management SudParis 9 Rue Charles Fourier 91011 Évry Cedex FRANCE Ankit Agarwal EPH Telecom Management SudParis 9 Rue Charles Fourier 91011 Évry Cedex FRANCE Patrick Horain EPH Telecom Management SudParis 9 Rue Charles Fourier 91011 Évry Cedex FRANCE Cindula Saipriyadarshan EPH Telecom Management SudParis 9 Rue Charles Fourier 91011 Évry Cedex FRANCE ABSTRACT This paper presents GpuCV an open source multi-platform library for easily developing GPU-accelerated image processing and Computer Vision operators and applications. It is meant for computer vision scientist not familiar with GPU technologies. It is designed to be compatible with Intel s OpenCV library by offering GPU-accelerated operators that can be integrated into native OpenCV applications. The GpuCV framework transparently manages hardware capabilities data synchronization activation of low level GLSL and CUDA programs on-the-fly benchmarking and switching to the most efficient implementation and finally offers a set of image processing operators with GPU acceleration available.
