Description

OpenCV 3 is a native cross-platform C Library for computer vision, machine learning, and image processing. Computer vision applications are the latest buzz of recent ! Big brands such as Microsoft, Apple, Google, Facebook, and Apple are increasingly making use of computer vision for object, pattern, image, and face recognition. This has led to a very high demand for computer vision expertise. So, if you're interested to know how to use the OpenCV library to build computer vision applications, then go for this Learning Path.

Packt’s Video Learning Paths are a series of individual video products put together in a logical and stepwise manner such that each video builds on the skills learned in the video before it.

The highlights of this Learning Path are

Dive into the essentials of OpenCV and build your own projects

Learn how to apply complex visual effects to images

Reconstruct a 3D scene from images

Master the fundamental concepts in computer vision and image processing

Let’s take a quick look at your learning journey. This Learning Path helps you to get started with the OpenCV library and shows you how to install and deploy it to write effective computer vision applications following good programming practices. You will learn how to read and display images. You will then be introduced to the basic OpenCV data structures.

Further, you will start a new project and see how to load an image file and show it. Next, you'll find out how to handle keyboard events in our display window. In the next project, you will jump into interactively adjusting image brightness. You will then learn to add a miniaturizing tilt-shift effect and how to blur images. In the final project, you will learn to apply Instagram-like color ambiance filters to images.

By the end of this Learning Path, you will be able to build computer vision applications that make the most of OpenCV 3.
