This chapter described the method to access pixel intensities at a particular location in an image. It is very useful when we are performing a pointwise operation on an image. A histogram is a very important global feature used to describe an image. This chapter described the method to compute a histogram and the process of histogram equalization, which improves the visual quality of an image. Various geometric transformations such as image resizing, rotation, and translation were explained in detail. Image filtering is a useful neighborhood processing technique used to eliminate noise and extract edge features of an image and was described in detail. A low pass filter is used to remove noise but it will also blur out the edges of an image. A high-pass filter removes the background, which is a low-frequency region while enhancing edges, which are high-frequency regions...

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.
