Face Tracking lets you accurately detect and track human faces. However, with Face Tracking, you can track specific parts of the face such as pupils, mouth, and nose, allowing you to isolate and work on these facial features with greater detail.
For example, change colors of the eyes or exaggerate mouth movements without frame-by-frame adjustments. After Effects also lets you measure facial features. Tracking of facial measurements tells you details such as how open the mouth or an eye is. With each data point isolated, you could greatly refine content.
Furthermore, you can also export detailed tracking data to Adobe Character Animator for performance-based character animation. The face tracker works largely automatically, but you can obtain better results by starting the analysis on a frame showing a front, upright view of the face. Adequate lighting on the face can improve the accuracy of face detection.General switch panel 100 amp 3518 fused full
The effect contains several 2D effect control points with keyframes, each of which is attached to detected facial features for example, the corners of the eyes and mouth, locations of pupils, the tip of the nose. Browse to the location of the footage, and add it to the Project. Position the current time indicator CTI to a frame showing a front, upright view of the face you want to track.
Note: Face detection is improved if the initial frame to track has a face looking forward and is oriented upright. Draw a closed mask loosely around the face, enclosing the eyes and mouth. The mask defines the search region to locate facial features. If multiple masks are selected, the topmost mask is used. In the Tracker panel, track forward or backward one frame at a time to ensure that tracking is functioning correctly, and then, click the button to begin analyzing all frames.
Once the analysis is complete, face tracking data is made available within the composition. Position the Current Time Indicator to a frame showing a front, upright view of the face you want to track. After the analysis is complete, the tracking data is made available within a new Effect called Face Track Points. Move the current-time indicator to a frame showing a neutral expression on the face the rest pose. Face measurements on other frames are relative to the rest pose frame.
In the Tracker panel, click Set Rest Pose. A Face Measurements effect is added to the layer, and keyframes are created based on calculations made from the Face Track Points keyframe data. The Face Measurements keyframe data is copied to the system clipboard for use in Character Animator.
The Face Tracker effect creates effect control points for several facial features, which you can view in the Timeline panel. If you have used the Detailed Features option, you can extract even more information in the form of parametric measurements of facial features, known as Face Measurements. All measurements shown for the face you tracked are relative to the Rest Pose frame. The following data points are made available indicating offset values on x, y, and z axes:.It provides code samples as well as useful tips on how to call its APIs to get the most out of the face tracking engine.
It can be used for markerless tracking of human faces with Kinect camera attached to a PC. The face tracking engine computes 3D positions of semantic facial feature points as well as a 3D head pose. The Face Tracking SDK could be used to drive virtual avatars, recognize facial expressions, Natural User Interfaces and other face related computer vision tasks.Ox bile side effects
You need to have Kinect camera attached to your PC. The Face Tracking engine tracks faces at the speed of ms per frame depending on your PC resources.

This picture demonstrates the results of face tracking. This video demonstrates the face tracking capabilities, supported range of motions and few limitations.
You also need to link with the provided FaceTrackLib. These DLLs must be located in the working directory of your executable or in the globally searchable paths. To create a face tracker instance do this:. Next, you need to initialize the created face tracker with Kinect camera configuration parameters.
The face tracker uses both cameras to increase face tracking accuracy. Camera configuration parameters must be precise, so it is better to use constants defined in NuiAPI.
If can combine Kinect camera with an external HD camera to increase precision and range. In this case, you need to pass correct focal length and resolution parameters in the camera configuration structure.
Also, if you use an external camera, you need to provide a depth frame to video frame mapping function, since the default Kinect function works only for Kinect cameras. Also, you need to create an instance of a face tracking result object that receives the 3D tracking results like this:. If you wrap your buffers then you need to fill them with RGB and depth data from Kinect camera. If you let IFTImage to own its memory, then you need to fill its memory with video and depth frame data from corresponding Kinect cameras.
The face tracking SDK requires that you pass both video and depth frames to track faces.Multi-face tracking in unconstrained videos is a challenging problem as faces of one person often appear drastically different in multiple shots due to significant variations in scale, pose, expression, illumination, and make-up. Existing multi-target tracking methods often use low-level features which are not sufficiently discriminative for identifying faces with such large appearance variations.
In this paper, we tackle this problem by learning discriminative, video-specific face representations using convolutional neural networks CNNs. Unlike existing CNN-based approaches which are only trained on large-scale face image datasets offline, we use the contextual constraints to generate a large number of training samples for a given video, and further adapt the pre-trained face CNN to specific videos using discovered training samples.
Using these training samples, we optimize the embedding space so that the Euclidean distances correspond to a measure of semantic face similarity via minimizing a triplet loss function. With the learned discriminative features, we apply the hierarchical clustering algorithm to link tracklets across multiple shots to generate trajectories.
We extensively evaluate the proposed algorithm on two sets of TV sitcoms and YouTube music videos, analyze the contribution of each component, and demonstrate significant performance improvement over existing techniques.
We tackle the problem of tracking multiple faces of people while maintaining their identities in unconstrained videos. Such videos consist of many shots from different cameras. The main challenge is to address large appearance variations of faces from different shots due to changes in pose, view angle, scale, makeup, illumination, camera motion and heavy occlusions.
Our multi-face tracking algorithm has four main steps: a Pre-training a CNN on a large-scale face recognition dataset to learn identity-preserving features, b Generating face pairs or face triplets from the tracklets in a specific video with the proposed spatio-temporal constraints and contextual constraints, c Adapting the pre-trained CNN to learn video-specific features from the automatically generated training samples, and d Linking tracklets within each shot and then across shots to form the face trajectories.
Here, we label the faces in T 1 and T 3 as the same identity given the sufficiently high similarity between the contextual features of T 1 and T 3.
The ideal line indicates that all faces are correctly grouped into ideal clusters, and its corresponding weighted purity is equal to 1. For the more effective feature, its purity approximates to 1 faster with the increase in the number of clusters. The legend contains the purities at the ideal number of clusters for each feature.

The moment I heard about this project, I knew I wanted to be involved :. During the course of the project, we got asked whether we would be able to have the robot ready before the 18th of November: Deloitte was sponsoring the TEDx in Amsterdam and it would be great to show the robot at the Deloitte stand.
Fortunately, we were able to finish everything before the 18th:. Although the robot is visible in the picture above, being held by Naser Bakhshi, you cannot see it that well, so below a close-up of the robot we demonstrated at the TEDx:.
As mentioned, one of the features of our robot is that it will do face recognition. In order do this, the first thing we will have to do is to detect faces and keep tracking them.
In this blog post, I want to focus on showing how we made use of Python and OpenCV to detect a face and then use the dlib library to efficiently keep tracking the face.
After we decided to make use of Python, the first feature we would need for performing face recognition is to detect where in the current field of vision a face is present. During the implementation, we made use of Anaconda with Python 3. If you want to use the code in this article, please make sure that you have these or newer versions. The rest of the code will be an infinite loop that retrieves the latest image from the webcam, detects all faces within the image, draws a rectangle around the largest face, and finally shows the output in a window.
A better approach for this is to do the detection of the face once and then use the correlation tracker from the excellent dlib library to just keep track of the relevant region from frame to frame.
Within the infinite for-loop, we will now have to determine if the dlib correlation tracker is currently tracking a region in the image. If this is not the case, we will use a similar code as before to find the largest face, but instead of drawing the rectangle, we use the found coordinates to initialize the correlation tracker. Now the final bit within the infinite loop is to check again if the correlation tracker is actively tracking a face i.
If the tracker is actively tracking a face in the image, we will now update the tracker. Depending on the quality of the update i. As you can see in the code, we print a message to the console every time we use the detector again.
If you look at the output of the console while running this application, you will notice that even if you move quite a bit around on the screen, the tracker is quite good at following a face once it is detected. When using the above code, you should see a screen similar to the following, where the program indicates it detected my face:. The moment I heard about this project, I knew I wanted to be involved : During the course of the project, we got asked whether we would be able to have the robot ready before the 18th of November: Deloitte was sponsoring the TEDx in Amsterdam and it would be great to show the robot at the Deloitte stand.

The two components of the robot you cannot see are a laptop the actual brain of our robot and a router connecting the EV3 unit and the iPhone with the laptop. Detecting a face After we decided to make use of Python, the first feature we would need for performing face recognition is to detect where in the current field of vision a face is present.

If we omit the cast to int here, you will get cast errors since the detector returns numpy. If you have any updates, please fork and send me a pull request. Will also do some follow-up posts on how we did the face recognition.9kmovie trad
Share this.With some careful tweaking and code optimization I was able to allow the pi to keep up with two servos while running OpenCV face detection at x looking for a right profile,left profile, and frontal face and adjusting the servos faster than once per second.
Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson. Make sure you are using the Official RaspbianOS the hard-float version and that it is up to date.
You may want to overclock your raspberry pi. I did to mhz. The higher you go the faster the facial recognition will be, but the less stable your pi may be. Install OpenCV for python: sudo apt-get install python-opencv Get the wonderful servoblaster servo driver for the raspberry pi by Richard Hirst: here You can download all the files as a zip archive and extract them to a folder somewhere on the pi.
You may want to make servoblaster time-out and stop sending signals to the servo after a second if it's not being moved.
Attach your camera to the top of the bracket i just used tape and plug it into your raspberry pi usb port. I was able to power it without a usb hub, but you may want to get a powered usb hub and go through that.
The code assumes that servo-0 will control the left-right movement and servo-1 will control the up-down movement of the camera; so connect them this way. Now it would seem to be common sense that the Vin for the servos would come from the 5v pins from the GPIO and the ground for the servos would come from the ground pins of GPIO, but this did not work in my case because I used a larger servo for the base.
The large servo pulled more power than the pi was willing so supply. I was, however, able to power my smaller tilt servo with no issue. I have also learned that there are some fuses in my version of the pi that were later removed related to those power pins.
My instinct tells me that you could power two smaller servos from those pins on a newer pi. If you cannot, this is what you will have to do: You will need some kind of external power source which is able to handle a heavy 5v-6v load: I used the one built into an arduino, but any 5ish volt power source should do; the servos are rated for up to 6v. Hello, I want to try this one but I can't find the download for the "PiFace. Can somebody help me? Reply 6 years ago.
