Modnet matting model reproduction

---

Preface

MODNet By the City University of Hong Kong and Shangtang technology in 2020 year 11 First proposed in , For real-time matting tasks . The model is excellent , Matting can be achieved without background input , And the real-time performance is very high . But the official code does not give a complete training example , I am here github A complete reproduction example is given on , stay B standing Give a rough explanation of the principle .
