Basic Learning notes: opencv (1): An Example of facedetect in opencv

A mainstream face detection method is like Haar + embedding sting, which is also used in opencv. This method can be applied to the detection of rigid objects, provided that the cascade classifier (for example, the Haar-like feature) is trained. Once the training data is completed, the cascadeclassifier class in opencv is called directly, you can use several simple member functions to complete the detection function. Therefore, it is very easy to use. The following is an example of facedetect in
