The neural net is equivalent to the FaceRecognizerNet used in face-recognition.js and the net used in the dlib face recognition example. You can determine the similarity of two arbitrary faces by comparing their face descriptors, for example by computing the euclidean distance or using any other classifier of your choice. The model is not limited to the set of faces used for training, meaning you can use it for face recognition of any person, for example yourself. The models have been trained on a dataset of ~35k face images labeled with 68 face landmark points.įor face recognition, a ResNet-34 like architecture is implemented to compute a face descriptor (a feature vector with 128 values) from any given face image, which is used to describe the characteristics of a persons face. Both models employ the ideas of depthwise separable convolutions as well as densely connected blocks. The default model has a size of only 350kb ( face_landmark_68_model) and the tiny model is only 80kb ( face_landmark_68_tiny_model). This package implements a very lightweight and fast, yet accurate 68 point face landmark detector. and the model weights are provided in the official repo of the MTCNN implementation. MTCNN has been presented in the paper Joint Face Detection and Alignment using Multi-task Cascaded Convolutional Networks by Zhang et al. MTCNN is a 3 stage cascaded CNN, which simultaneously returns 5 face landmark points along with the bounding boxes and scores for each face. By tuning the input parameters, MTCNN should be able to detect a wide range of face bounding box sizes. MTCNN (Multi-task Cascaded Convolutional Neural Networks) represents an alternative face detector to SSD Mobilenet v1 and Tiny Yolo v2, which offers much more room for configuration. In general the other face detectors should perform better, but of course you are free to play around with MTCNN. Note, this model is mostly kept in this repo for experimental reasons. Yolo is fully convolutional, thus can easily adapt to different input image sizes to trade off accuracy for performance (inference time). This model is basically an even tinier version of Tiny Yolo V2, replacing the regular convolutions of Yolo with depthwise separable convolutions. Furthermore the model has been trained to predict bounding boxes, which entirely cover facial feature points, thus it in general produces better results in combination with subsequent face landmark detection than SSD Mobilenet V1. The face detector has been trained on a custom dataset of ~14K images labeled with bounding boxes. The size of the quantized model is only 190 KB ( tiny_face_detector_model). This model is extremely mobile and web friendly, thus it should be your GO-TO face detector on mobile devices and resource limited clients. The Tiny Face Detector is a very performant, realtime face detector, which is much faster, smaller and less resource consuming compared to the SSD Mobilenet V1 face detector, in return it performs slightly less well on detecting small faces. The face detection model has been trained on the WIDERFACE dataset and the weights are provided by yeephycho in this repo. The size of the quantized model is about 5.4 MB ( ssd_mobilenetv1_model). This face detector is aiming towards obtaining high accuracy in detecting face bounding boxes instead of low inference time. The neural net will compute the locations of each face in an image and will return the bounding boxes together with it's probability for each face.
