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.

Deploying Computer Vision Applications on Jetson TX1

The previous chapter described the installation of OpenCV and CUDA on a Jetson TX1 development board. This chapter will describe how to use these features on the board. The properties of the Jetson TX1 GPU that make it useful for parallel processing will be described in detail. The chapter will also describe how we can execute the CUDA and C++ codes, seen earlier in this book, on Jetson TX1. It will also demonstrate the performance of the Jetson TX1 GPU in executing CUDA code. The primary motive of this chapter will be to demonstrate the use of Jetson TX1 in deploying image- and video-processing applications. Basic image-processing applications such as image reading, displaying, addition, thresholding, and filtering are taken as examples to demonstrate the use of Jetson TX1 for computer vision applications. Moreover, camera...
