Although Bayesian classifiers are relatively simple to implement, the theory behind them can be quite counter-intuitive at first, especially if you are not too familiar with probability theory yet. However, the beauty of Bayesian classifiers is that they understand the underlying data better than all of the classifiers we have encountered so far. For example, standard classifiers, such as the k-nearest neighbor algorithm or decision trees, might be able to tell us the target label of a never-before-seen data point. However, these algorithms have no concept of how likely it is for their predictions to be right or wrong. We call them discriminative models. Bayesian models, on the other hand, have an understanding of the underlying probability distribution that caused the data. We call them generative models because they don't just put labels...

Overview of this book
OpenCV is an opensource library for building computer vision apps. The latest release, OpenCV 4, offers a plethora of features and platform improvements that are covered comprehensively in this up-to-date second edition.
You'll start by understanding the new features and setting up OpenCV 4 to build your computer vision applications. You will explore the fundamentals of machine learning and even learn to design different algorithms that can be used for image processing. Gradually, the book will take you through supervised and unsupervised machine learning. You will gain hands-on experience using scikit-learn in Python for a variety of machine learning applications. Later chapters will focus on different machine learning algorithms, such as a decision tree, support vector machines (SVM), and Bayesian learning, and how they can be used for object detection computer vision operations. You will then delve into deep learning and ensemble learning, and discover their real-world applications, such as handwritten digit classification and gesture recognition. Finally, you’ll get to grips with the latest Intel OpenVINO for building an image processing system.
By the end of this book, you will have developed the skills you need to use machine learning for building intelligent computer vision applications with OpenCV 4.
