How are cracks detected?

Crack detection is the process of detecting the crack in the structures using any of the processing techniques. The crack detection can be made in two ways. They are Destructive Testing and Non-Destructive testing.

What can OpenCV detect?

OpenCV is the huge open-source library for computer vision, machine learning, and image processing and now it plays a major role in real-time operation which is very important in today's systems. By using it, one can process images and videos to identify objects, faces, or even the handwriting of a human.

What is used to OpenCV is used to detect edges of the image?

In this article, the popular canny edge detection algorithm is used to detect a wide range of edges in images. OpenCV has in-built function cv2. Canny() which takes our input image as first argument and its aperture size(min value and max value) as last two arguments.
