python的opencv库使用gpu加速_基于OpenCV/CUDA的GPU加速计算机视觉实战
Hands-On-GPU-Accelerated-Computer-Vision-with-OpenCV-and-CUDA
Hands-On GPU Accelerated Computer Vision with OpenCV and CUDA, published by Packt
**Effective techniques for processing complex image data in real time using GPUs **
What is this book about?
Computer vision has been revolutionizing a wide range of industries, and OpenCV is the most widely chosen tool for computer vision with its ability to work in multiple programming languages. Nowadays, in computer vision, there is a need to process large images in real time, which is difficult to handle for OpenCV on its own. This is where CUDA comes into the picture, allowing OpenCV to leverage powerful NVDIA GPUs. This book provides a detailed overview of integrating OpenCV with CUDA for practical applications.
This book covers the following exciting features: Understand how to access GPU device properties and capabilities from CUDA programs
Learn how to accelerate searching and sorting algorithms
Detect shapes such as lines and circles in images
Explore object tracking and detection with algorithms
Process videos using different video analysis techniques in Jetson TX1
Access GPU device properties from the PyCUDA program
Understand how kernel execution works

Instructions and Navigations
All of the code is organized into folders. For example, Chapter02.
The code will look like the following:while (tid < N)
{
d_c[tid] = d_a[tid] + d_b[tid];
tid += blockDim.x * gridDim.x;
}
Following is what you need for this book: This book is a go-to guide for you if you are a developer working with OpenCV and want to learn how to process more complex image data by exploiting GPU processing. A thorough understanding of computer vision concepts and programming languages such as C++ or Python is expected.
With the following software and hardware list you can run all code files present in the book (Chapter 1-12).
