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.

Questions

  1. Compare the performance of a GPU device on Jetson TX1 with a GeForce 940 GPU seen earlier in the book.
  2. State True or False: All CUDA programs seen earlier in the book can be executed on Jetson TX1 without modification.
  3. What is the need for recompiling OpenCV on Jetson TX1?
  4. State True or False: OpenCV can't capture video from a camera connected to the USB port.
  5. State True or False: It is better to use a CSI camera for computationally intensive applications than a USB camera.
  6. If you are developing computationally intensive computer vision applications using OpenCV, which language would you prefer for faster performance?
  7. Is there a need to install separate OpenCV Python binding or Python interpreter on Jetson TX1?
