This chapter described the role of OpenCV and CUDA in real-time object detection and tracking applications. It started with the introduction of object detection and tracking, along with challenges encountered in that process and the applications of it. Different features like color, shape, histograms, and other distinct key-points, like corners, can be used to detect and track objects in an image. Color-based object detection is easier to implement, but it requires that the object should have a distinct color from the background. For shape-based object detection, the Canny edge detection technique has been described to detect edges, and Hough transform has been described for straight line and circle detection. It has many applications, such as land detection, ball tracking, and so on. The color and shape are global features, which are easier to compute and require less...

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.
