This repository provides tutorials and code examples for running computer vision and machine learning tasks in PHP using the OpenCV library. It covers face detection using cascade classifiers and DNN modules, facial landmark detection with LBF algorithm, face recognition via LBPH and deep neural networks (OpenFace, InsightFace), image upscaling with waifu2x, and image classification using models like MobileNet. The examples utilize pre-trained models from Caffe, TensorFlow, Darknet, and ONNX formats.
