Facial recognition technology has a variety of applications and beneficial use cases in both the front end and back end of businesses all over the world. A face recognition model is trained to interpret human faces and differentiate between different faces.

Whereas a human sees a face, a facial recognition model sees a myriad of calculations. For use in surveillance and security, the model could then compare those calculations to other faces in their database to find a match. Those calculations could also be used to find the correct position to anchor digital image filters in photo face recognition tools like face filters in mobile apps.

Regardless of the use case, all facial recognition models require large amounts of face image data to train. To create accurate facial recognition technology, the models need to be trained on face images varying in age, ethnicity, and photo environment conditions (angle, lighting, etc.). Lionbridge has staff located in every continent, ready to create or annotate your face image training data.

Our Services for Facial Recognition

Whether you require face image data collection or face image data annotation, our global crowd of 500,000+ contributors can fulfill your training data needs quickly and at scale.

Face Image Data Collection

With all facial recognition models, the more data you feed it the stronger and more accurate the model will become.

Having a global crowd means that we can source face images from contributors all over the world who vary in age and ethnicity, allowing your face recognition model to be trained on a diverse corpus of face images. Depending on the needs of your project, we can set strict guidelines for how each image is taken, including lighting conditions, angle, facial emotion/gesture, image format, and resolution.

Face Image Annotation

For the training of facial recognition solutions, sourcing the face images is half the battle. The more challenging task is annotating the images with facial keypoints.

Lionbridge provides facial landmark annotation (also known as keypoints annotation) for facial recognition, gesture labelling, and emotion detection. While a relatively straightforward task, it is more efficient for developers to outsource facial landmark annotation when handling large quantities of data. For example: 2000 images with 68 facial landmarks per image would amount to a total of 136,000 landmarks to be annotated and evaluated for accuracy.

Instead of licensing a landmark annotation platform, finding annotation staff, training staff to annotate the data, reviewing the data for accuracy, and formatting the data all on your own, Lionbridge can do all of this for you.

Lionbridge can:

  • Source face images
  • Leverage and train our crowd to annotate your image data on our platform
  • Review the data for accuracy and quality assurance
  • Create the data files in your desired formats

Our expert annotators come pre-trained on our proprietary image annotation platform and we don’t charge any platform fees. After a short training phase where we train our crowd on your specific project’s requirements, we will be able to annotate thousands of face images with a short turnaround time.

Outsource face image annotation with ease.
