The WIDER FACE dataset is a face detection benchmark dataset. Firstly, we get the image with the face and run it through a cascade classifier. Sporting a mask may be necessary in the near future, considering the COVID-19 crisis and this method to detect if the person wears a face mask may come in handy. Take a look, export PYTHONPATH=$PYTHONPATH:/home/dion/models/research:/home/dion/models/research/slim. [2] https://github.com/VisualDataNetwork/root. When the data is converted to Pascal XML, an index is created. For validation, two variables are important. Photo by Macau Photo Agency on Unsplash. A name and a password are requested (the name is not actually necessary, it’s requested just to show a greeting in your profile). For this tutorial we use only the slim and object_detection module. If we deployed it correctly, we can help ensure the safety of others. I had some experience with the TensorFlow Object Detection API. Python Code: Server Code: Client Read more…. I hope it’ll be useful for someone. In this blogpost I will focus on training a object detector with customized classes. I am going to use these images to build a CNN model using TensorFlow to detect if you are wearing a face mask by using the webcam of your PC. After that, we need to have all the images in the same size (100x100) before applying it to the neural network. Q-1. The Chinese University of Hong Kong has WIDERFace and this dataset has been used to train model. AI as a Service: Face Detection Using MTCNN • 5 minutes to read. The model released by this repo.
