Try a live demo here. PoseNet can detect human figures in images and videos using either a single-pose algorithm So what is pose estimation anyway? To be clear, this technology is not recognizing who is in an image — there is no personal identifiable information associated to pose detection.

The algorithm is simply estimating where key body joints are. Ok, and why is this exciting to begin with? Pose estimation has many uses, from interactive installations that react to the body to augmented realityanimationfitness usesand more. We hope the accessibility of this model inspires more developers and makers to experiment and apply pose detection to their own unique projects.

With PoseNet running on TensorFlow. Since PoseNet on TensorFlow. Why are there two versions? The single person pose detector is faster and simpler but requires only one subject present in the image more on that later. At a high level pose estimation happens in two phases: An input RGB image is fed through a convolutional neural network.

Either a single-pose or multi-pose decoding algorithm is used to decode poses, pose confidence scores, keypoint positions, and keypoint confidence scores from the model outputs. But wait what do all these keywords mean? PoseNet returns confidence values for each person detected as well as each pose keypoint detected. It ranges between 0. It can be used to hide poses that are not deemed strong enough. It contains both a position and a keypoint confidence score. PoseNet currently detects 17 keypoints illustrated in the following diagram: Seventeen pose keypoints detected by PoseNet.

Keypoint Confidence Score — this determines the confidence that an estimated keypoint position is accurate.Tutorials show you how to use TensorFlow.

The key points detected are indexed by "Part ID", with a confidence score between 0. Performance benchmark numbers are generated with the tool described here. Performance varies based on your device and output stride heatmaps and offset vectors. The PoseNet model is image size invariant, which means it can predict pose positions in the same scale as the original image regardless of whether the image is downscaled.

This means PoseNet can be configured to have a higher accuracy at the expense of performance. It affects the size of the layers and the model outputs.

The higher the output stride, the smaller the resolution of layers in the network and the outputs, and correspondingly their accuracy. In this implementation, the output stride can have values of 8, 16, or In other words, an output stride of 32 will result in the fastest performance but lowest accuracy, while 8 will result in the highest accuracy but slowest performance.

We recommend starting with A higher output stride is faster but results in lower accuracy. Except as otherwise noted, the content of this page is licensed under the Creative Commons Attribution 4.

I've taken a few pre-trained models and made an interactive web thing for trying them out. Chrome is recommended. The pix2pix model works by training on pairs of images such as building facade labels to building facades, and then attempts to generate the corresponding output image from any input image you give it.

The idea is straight from the pix2pix paperwhich is a good read. Trained on about 2k stock cat photos and edges automatically generated from those photos.

Generates cat-colored objects, some with nightmare faces. The best one I've seen yet was a cat-beholder. Some of the pictures look especially creepy, I think because it's easier to notice when an animal looks wrong, especially around the eyes. The auto-detected edges are not very good and in many cases didn't detect the cat's eyes, making it a bit worse for training the image translation model.

Trained on a database of building facades to labeled building facades. It doesn't seem sure about what to do with a large empty area, but if you put enough windows on there it often has reasonable results. Draw "wall" color rectangles to erase things. I didn't have the names of the different parts of building facades so I just guessed what they were called.

If you're really good at drawing the edges of shoes, you can try to produce some new designs. Keep in mind it's trained on real objects, so if you can draw more 3D things, it seems to work better. If you draw a shoe here instead of a handbag, you get a very oddly textured shoe. The models were trained and exported with the pix2pix. The interactive demo is made in javascript using the Canvas API and runs the model using deeplearn.

The pre-trained models are available in the Datasets section on GitHub. All the ones released alongside the original pix2pix implementation should be available. The models used for the javascript implementation are available at pix2pix-tensorflow-models. The edges for the cat photos were generated using Holistically-Nested Edge Detection and the functionality was added to process.

July 19, Posted by Jane Friedhoff and Irene AlvaradoCreative Technologists, Google Creative Lab Pose estimation, or the ability to detect humans and their poses from image data, is one of the most exciting — and most difficult — topics in machine learning and computer vision.

Recently, Google shared PoseNet : a state-of-the-art pose estimation model that provides highly accurate pose data from image data even when those images are blurry, low-resolution, or in black and white. This is the story of the experiment that prompted us to create this pose estimation library for the web in the first place. Months ago, we prototyped a fun experiment called Move Mirror that lets you explore images in your browser, just by moving around.

The experiment creates a unique, flipbook-like experience that follows your moves and reflects them with images of all kinds of human movement — from sports and dance to martial arts, acting, and beyond.

We wanted to release the experience on the web, let others play with it, learn about machine learning, and share the experience with friends.

Unfortunately we faced a problem: a publicly accessible web-specific model for pose estimation did not exist. We thus saw a unique opportunity to make pose estimation more widely accessible by porting an in-house model to TensorFlow.

With PoseNet out in the wild, we can finally release Move Mirror — a project that is a testament to the value that experimentation and play can add to serious engineering work.

It was only through a true collaboration between research, product, and creative teams that we were able to build PoseNet and Move Mirror. What is pose estimation? What is posenet?

We want our machine learning models to be able to understand and smartly infer data about all these different bodies. In the past, technologists have approached the problem of pose estimation using special cameras and sensors like stereoscopic imagery, mocap suits, and infrared cameras as well as computer vision techniques that can extract pose estimation from 2d images like OpenPose.

This makes it harder for the average developer to quickly get started with playful pose experiments. All of a sudden, we could prototype pose estimation experiments quickly and easily in Javascript. This hugely lowered the barrier to entry for making small exploratory pose experiments: just a few lines of JavaScript, an API key, and we were set!

But of course, not everyone would have the capacity to run their own PoseNet backend, and reasonably not everyone would feel comfortable sending photos of themselves to a centralized server anyway.

This was the perfect opportunity, we realized, to connect TensorFlow. By porting PoseNet to TensorFlow. You can read more about that process here. A few things that made us super excited about PoseNet in TensorFlow. Shareability: Because everything can run in the browser, TensorFlow. No need to make operating-system-specific builds — just upload your webpage and go.

Privacy: Because all of the pose estimation can be done in the browser, that means none of your image data ever has to leave your computer. Rather than sending your photos to some server in the sky to do pose analysis on a centralized service i. With Move Mirror, we match the x,y joint data that PoseNet spits out with our bank of poses on our backend — but your image stays entirely on your computer. Design and Inspiration We spent a few weeks just goofing around with different pose estimation prototypes.

We played with trails, puppets, and all sorts of other silly things before we landed on the concept that would become Move Mirror. In talking about what we could do with pose estimation, we were tickled by the idea of being able to search an archive by pose.

What if you could strike a pose and get a result that was the dance move you were doing?Or use one of these example images that we obtained from the internet:. We have localised your input image on the map below! The blue arrow shows where we think you are. The image must have been taken within the blue highlighted region on the map. We have applied deep convolutional neural networks to camera pose regression.

Our system is simple in the fact that we train a system end-to-end to regress camera pose. Unlike other systems ours does not require a large database or landmarks. Instead, it learns robust high level features. It can deal with many different camera types, motion blur, weather, pedestrians and other distractions. It is highly scalable, requiring only a few MB of memory, and Our system requires training data to learn to localise in an environment.

We leverage transfer learning from large scale classification datasets to learn with relatively small amounts of training data.

We show that we can learn a smooth function of camera pose which can operate throughout the scene. This image shows training examplestesting examples and our resulting pose prediction in red.

PoseNet was trained with the Cambridge Landmarks Dataset. This is a large urban relocalisation dataset with 6 scenes from around Cambridge University containing over 12, images labelled with their full 6-DOF camera pose.

You can download the dataset from Cambridge University DSpace using the links below. A selection can be visualised online in your browser. Each scene contains the training and testing images.
