Hands-On GPU-Accelerated Computer Vision with OpenCV and CUDA

Overview of this book

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. To start with, you’ll understand GPU programming with CUDA, an essential aspect for computer vision developers who have never worked with GPUs. You’ll then move on to exploring OpenCV acceleration with GPUs and CUDA by walking through some practical examples. Once you have got to grips with the core concepts, you’ll familiarize yourself with deploying OpenCV applications on NVIDIA Jetson TX1, which is popular for computer vision and deep learning applications. The last chapters of the book explain PyCUDA, a Python library that leverages the power of CUDA and GPUs for accelerations and can be used by computer vision developers who use OpenCV with Python. By the end of this book, you’ll have enhanced computer vision applications with the help of this book's hands-on approach.

Summary

In this chapter, we started with the introduction of computer vision and image processing. We described OpenCV library, which is specifically made for computer vision applications, and how it is different from other computer vision software. OpenCV can leverage the parallel processing capability of GPU by using CUDA. We looked at the installation procedure for OpenCV with CUDA in all operating systems. We described the process to read an image from disk, display it on screen, and save it back to disk. Videos are nothing more than a sequence of images. We learned to work with videos from disk as well as videos captured from camera. We developed several image processing applications that do different operations on images, such as arithmetic operations, logical operations, color space conversions, and thresholding. In the last section, we compared the performance of the...
