Overview of this book

Computer vision is found everywhere in modern technology. OpenCV for Python enables us to run computer vision algorithms in real time. With the advent of powerful machines, we are getting more processing power to work with. Using this technology, we can seamlessly integrate our computer vision applications into the cloud. Web developers can develop complex applications without having to reinvent the wheel. This book will walk you through all the building blocks needed to build amazing computer vision applications with ease. We start off with applying geometric transformations to images. We then discuss affine and projective transformations and see how we can use them to apply cool geometric effects to photos. We will then cover techniques used for object recognition, 3D reconstruction, stereo imaging, and other computer vision applications. This book will also provide clear examples written in Python to build OpenCV applications. The book starts off with simple beginner’s level tasks such as basic processing and handling images, image mapping, and detecting images. It also covers popular OpenCV libraries with the help of examples. The book is a practical tutorial that covers various examples at different levels, teaching you about the different functions of OpenCV and their actual implementation.

Chapter 2. Detecting Edges and Applying Image Filters

In this chapter, we are going to see how to apply cool visual effects to images. We will learn how to use fundamental image processing operators. We are going to discuss edge detection and how we can use image filters to apply various effects on photos.

By the end of this chapter, you will know:

  • What is 2D convolution and how to use it
  • How to blur an image
  • How to detect edges in an image
  • How to apply motion blur to an image
  • How to sharpen and emboss an image
  • How to erode and dilate an image
  • How to create a vignette filter
  • How to enhance image contrast
