Overview of this book

Computer Vision (CV) has become an important aspect of AI technology. From driverless cars to medical diagnostics and monitoring the health of crops to fraud detection in banking, computer vision is used across all domains to automate tasks. The Computer Vision Workshop will help you understand how computers master the art of processing digital images and videos to mimic human activities. Starting with an introduction to the OpenCV library, you'll learn how to write your first script using basic image processing operations. You'll then get to grips with essential image and video processing techniques such as histograms, contours, and face processing. As you progress, you'll become familiar with advanced computer vision and deep learning concepts, such as object detection, tracking, and recognition, and finally shift your focus from 2D to 3D visualization. This CV course will enable you to experiment with camera calibration and explore both passive and active canonical 3D reconstruction methods. By the end of this book, you'll have developed the practical skills necessary for building powerful applications to solve computer vision problems.

3. Working with Histograms

Overview

In this chapter, you will learn about histograms and the adjustment of image histograms to enhance subtle details such as the appearance of objects hidden in shadows and the improvement of contrast in dark images. Although image histograms are simple, you will find that they are really powerful tools for enhancing an image to achieve contrast adjustment and better visualization. In almost all of your image enhancement projects, histogram equalization will be an important step. You will test your knowledge with exercises and an end-of-chapter activity, where you will draw a rectangular bounding box on an image and enhance the contrast within that box. By the end of this chapter, you will be able to plot histograms of different channels of an image and equalize histograms of grayscale and color images using different methods.
