Machine Learning for OpenCV 4 - Second Edition

Having a look at supervised learning in OpenCV

Just knowing how supervised learning works is not going to be of any use if we can't put it into practice. Thankfully, OpenCV provides a pretty straightforward interface for all its statistical learning models, which includes all supervised learning models.

In OpenCV, every machine learning model derives from the cv::ml::StatModel base class. This is fancy talk for saying that if we want to use a machine learning model in OpenCV, we have to provide all of the functionality that StatModel tells us to. This includes a method to train the model (called train) and a method to measure the performance of the model (called calcError).

In Object-Oriented Programming (OOP), we deal primarily with objects ...
