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

If we match a template whose shape is `(51, 51, 3)` on an image whose shape is `(500, 500, 3)`, what will be the match image shape?

If we match a template whose shape is <code>(51, 51, 3)</code> on an image whose shape is <code>(500, 500, 3)</code>, what will be the match image shape?

We match a template of shape `(31, 31)` (height and width, respectively) on a source image whose shape is `(512, 512)`. If a high match pixel is found in the match image at location (x, y) = `(200, 100)`, what is the corresponding pixel location of the feature in the source image?

The moments of an image are defined by the following equation:
$m_{i,j}=\sum_{x} \sum_{y} x^i y^j I[x, y]$.

What does the image moment $m_{0,0}$ represent, for a binary image?
