The network itself was trained by Davis King on a dataset of ≈3 million images.

Our network architecture for face recognition is based on ResNet-34 from the Deep Residual Learning for Image Recognition paper by He et al., but with fewer layers and the number of filters reduced by half. Our network quantifies the faces, constructing the 128-d embedding (quantification) for each.įrom there, the general idea is that we’ll tweak the weights of our neural network so that the 128-d measurements of the two Will Ferrel will be closer to each other and farther from the measurements for Chad Smith. The third image is a random face from our dataset and is not the same person as the other two images.Īs an example, let’s again consider Figure 1 where we provided three images: one of Chad Smith and two of Will Ferrell.Two of these images are example faces of the same person.Here we provide three images to the network: Image credit: Adam Geitgey’s “Machine Learning is Fun” blog For the 2 face images of the same person, we tweak the neural network weights to make the vector closer via distance metric. The NN generates a 128-d vector for each of the 3 face images. Training the network is done using triplets:įigure 1: Facial recognition via deep metric learning involves a “triplet training step.” The triplet consists of 3 unique face images - 2 of the 3 are the same person. Instead, of trying to output a single label (or even the coordinates/bounding box of objects in an image), we are instead outputting a real-valued feature vector.įor the dlib facial recognition network, the output feature vector is 128-d (i.e., a list of 128 real-valued numbers) that is used to quantify the face. However, deep metric learning is different. And output a classification/label for that image.If you have any prior experience with deep learning you know that we typically train a network to: The secret is a technique called deep metric learning. So, how does deep learning + face recognition work? Understanding deep learning face recognition embeddings

We’ll start with a brief discussion of how deep learning-based facial recognition works, including the concept of “deep metric learning.”įrom there, I will help you install the libraries you need to actually perform face recognition.įinally, we’ll implement face recognition for both still images and video streams.Īs we’ll discover, our face recognition implementation will be capable of running in real-time.

Google started rolling out the feature to all Android phones with Google Photos installed earlier this month.Looking for the source code to this post? Jump Right To The Downloads Section Face recognition with OpenCV, Python, and deep learning Lens debuted last October on the Pixel 2 and Pixel 2 XL. The feature is rolling out to version 3.15 of the iOS app, so make sure you update. You can delete any history from your My Activity page at any time. Google notes that if your web and app activity setting is switched on, your Google Lens activity will be saved to your Google account. Depending on what the photo is, you can then check the details Google provides, or take an action. To access the feature on your iOS device, launch the Google Photos app, select a photo, then tap on the Google Lens icon. UyIkwAP3i9- Google Photos March 15, 2018 Make sure you have the latest version (3.15) of the app. Starting today and rolling out over the next week, those of you on iOS can try the preview of Google Lens to quickly take action from a photo or discover more about the world around you.
