OpenCV-GUI

OpenCV is extensively used in the business world for various applications, including facial recognition, object detection, and image and video manipulation. 

In this course, you'll learn the basics of OpenCV—an open-source machine learning library. You'll begin with an overview of the OpenCV library before moving on to practical applications like viewing images, videos, and webcam input. Next, you'll learn how to edit images with tools like decolorizing, cropping, resizing, and captioning. You'll dive into machine learning functions like edge detection, contour detection, corner detection, and face detection. Finally, you'll work on practical projects like document scanners and object trackers. 

By the end of this course, you’ll have a solid understanding of OpenCV and machine learning with C++. You'll be able to create functional applications using computer vision principles, preparing you for real-world projects. Taking this course will allow you to take your programming skills to the next level.

Learning OpenCV from Scratch with C++

In this lesson, we’ll use most of the OpenCV functions and techniques to create a document scanner. For that, we'll need an image that contains a document. The document scanner will find the edges of the document and crop the document, giving an output image containing the document only. The output image will remove any unnecessary areas outside the document. Follow the given steps, and write the code in the code widget at the end of the project.

We’ll create different functions to separate our work. First, we’ll import our libraries and image. You can even connect it to your webcam as a personal project.

# Get image edges
The basic purpose of a document scanner is to get the edges of our document. We use an edge detection technique to detect edges.


Follow step-by-step instructions to create a simple document scanner.
