An Introduction to Image Segmentation - How to Partition an Image into Segments

In this course we’ll build an app that can detect and recognize playing cards using Python and OpenCV. This app will detect that there is a playing card in an image, it grab all the cards it finds and reorients them.

There are two main concepts that will be covered in this course. One of them is thread-holding, which is a technique of image segmentation. The second one is contour detection.

Learning goals:

Thresholding
- Binary thresholding
- Inverted binary thresholding

Contour detection
- Curve approximation - Contour hierarchy
- Polygon approximation
