Computer vision is a rapidly evolving science, encompassing diverse applications and techniques. This book will not only help those who are getting started with computer vision but also experts in the domain. Youโll be able to put theory into practice by building apps with OpenCV 4 and Python 3.
Youโll start by understanding OpenCV 4 and how to set it up with Python 3 on various platforms. Next, youโll learn how to perform basic operations such as reading, writing, manipulating, and displaying still images, videos, and camera feeds. From taking you through image processing, video analysis, and depth estimation and segmentation, to helping you gain practice by building a GUI app, this book ensures youโll have opportunities for hands-on activities. Next, youโll tackle two popular challenges: face detection and face recognition. Youโll also learn about object classification and machine learning concepts, which will enable you to create and use object detectors and classifiers, and even track objects in movies or video camera feed. Later, youโll develop your skills in 3D tracking and augmented reality. Finally, youโll cover ANNs and DNNs, learning how to develop apps for recognizing handwritten digits and classifying a person's gender and age.
By the end of this book, youโll have the skills you need to execute real-world computer vision projects.
