C# Introduction to Face Recognition -Step ByStep Face Recognition Nowadays, face-based technologies and topics can be said to be very popular. Face recognition based on big data and artificial intelligence breaks through the limits of our imagination. If face recognition cannot be integrated into applications, it will be too behind the trend.Face recognition is an algorithm-intensive project. If it is developed by myself, it requires a deep foundation in mathematics

CV Deep Learning Model Android End Landing Scheme II: Real-time Face Detection Using Face Class and Frame Face

This series of blogs mainly introduce how to transplant your trained cv neural network model on Android devices. The main process is as follows:1. Use Android Camera2 APIs to get a real-time preview of the camera.2. If the Face image is processed, face detection is carried out by using the face class provided by Android Camera2, and the functions of framing the face on the preview screen and adding characters

I had nothing to do yesterday, and suddenly found myself unable to play Git. It is simply intolerable for a person who aspires to be a great technologist. As a result, I quickly filled in the tutorial, mainly on Liao Xuefeng's blog.https://www.liaoxuefeng.com/wiki/0013739516305929606dd18361248578c67b8067c8c017b000/00137628548491051ccfaef0ccb470894c858999603fedf000。For detailed tutorials, please refer to the novice tutorials and Liao Xuefeng's blog. Here are some common commands. Basic Grammar create version library: git init (use this command under a folder to make the directory gitmanageable)View status: git statusAdd file to staging area: git add fileAdd to branch: gitcommit-m' [message]'View log: git logConcise version log: gitlog–onelineRoll back to previous version: gitreset-hard head (several [] represent roll back to previous version and represent previous version.
