This chapter demonstrated the concepts of programming in PyCUDA. It started with the development of a simple Hello, PyCUDA program using PyCUDA. The concepts of kernel definition in C or C++ and calling it from Python code and the API for accessing GPU device properties from a PyCUDA program were discussed in detail. The execution mechanism for multiple threads and blocks in a PyCUDA program was explained with a simple program. The basic structure of a PyCUDA program was described with a simple example of an array addition. The simplification of PyCUDA code was described by using directives from a driver class. The use of CUDA events to measure the performance of the PyCUDA programs was explained in detail. The functionality of the inout directive of the driver class and the gpuarray class was explained using an element-wise squaring example. The gpuarray class was used...

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.
