Computer vision is essential for developers who wish to learn practical skills, e.g., in industrial manufacturing, automated inspection of products is crucial for quality assurance.

In this course, you’ll apply computer vision and machine learning to analyze images for automated inspection. You’ll start by learning image I/O operations, thresholding, smoothing, and masking. You’ll learn feature detection using template matching and morphology. You’ll use the Sobel and Canny Edge Detectors, Harris Corner Detector, and Hough transform. You’ll learn about 2D transformations, including perspective and affine transformation, and 3D-to-2D projections. You’ll perform topography with a laser line to inspect the 3D shape of an object. Lastly, you’ll train convolutional neural networks for object detection and image segmentation and annotate datasets using CVAT.

By the end of this course, you will have the skills to build inspection systems for industrial applications using computer vision and machine learning.

Automated Inspection with Computer Vision

We should design a template that captures the essential characteristics of the feature, and use template matching.

We should call the OpenCV function ```cv2.findCorners()```.

If we want to find specific features, such as the physical corners of an object, which strategy should we use?

If we want to find specific features, such as the physical corners of an object, which strategy should we use?

The object could be shifted in x- or y-axes with respect to the image center.

The object scale could change from one image to the next.

The object could appear rotated in the image plane.

When we want to find the corners of a rectangular object with template matching, what is the main problem we could face?

When we want to find the corners of a rectangular object with template matching, what is the main problem we could face?

**(True or False)** When we want to find the corners of a rectangular object with pattern matching, a single call to ```cv2.matchTemplate()``` is enough.

(True or False) When we want to find the corners of a rectangular object with pattern matching, a single call to <code>cv2.matchTemplate()</code> is enough.

Corners are points where the rate of change in grayscale is high in one direction only.

Corners are points where the rate of change in grayscale is high in two perpendicular directions.

Corners in an image are caused by a three dimensional physical corner.

The appearance of a corner is impacted by imperfect focus.
