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

Training neural networks and monitoring the evolution of the losses

Acting as a hub where we can download pretrained CNN weights

Locating objects (through a bounding box or a mask) in images from a dataset

Rating public image datasets so users know which ones are of the best quality

What is the use of the CVAT image annotation tool?

What is the use of the CVAT image annotation tool?

Search for a pretrained CNN that does exactly what you need.

Pass the images of defects through a generic pretrained CNN, and figure out how the CNN output maps with the type and location of the defect.

Annotate an image dataset of the product with all the known defect types, then use transfer learning or fine-tuning of a pretrained CNN on this dataset.

Get a pretrained CNN and train it on your defect dataset from scratch.

Suppose you need to locate defects in images of a unique product manufactured by your company, how can you leverage pretrained CNNs?

**(True or False)** The polygon annotation tool can only create quadrilaterals.

(True or False) The polygon annotation tool can only create quadrilaterals.

**(True or False)** With the polygon annotation tool, we must know in advance how many vertices the polygon will have, before selecting any point.

(True or False) With the polygon annotation tool, we must know in advance how many vertices the polygon will have, before selecting any point.

Objects of the same category or label get the same arbitrary color.

The object contrast is increased for a better visibility.

All objects found in a given image, no matter their label, get the same color.

What is the meaning of the highlighting color in the image annotation environment?

**(True or False)** An object can partially occlude another object.

(True or False) An object can partially occlude another object.
