Face++ detect performance report


According to the FDDB (Face Detection Data Set and Benchmark) report, Face++ delivers state-of-the-art face detection performance among its commercial competitors.

FDDB is a data set of face regions designed for studying the problem of unconstrained face detection. This data set contains the annotations for 5171 faces in a set of 2845 images taken from the Faces in the Wild data set.

In the below diagrams, the horizontal axis represents the number of false positive faces reported by the detector, while the vertical one shows the true positive rate. The closer the curve approaches to the upper-left corner, the better the corresponding detector does on this benchmark.


It can be seen from the discrete score diagram, Face++ holds the best performance 0.8 TPR (True positive rate) with nearly 30 false positives. Notice that, in continuous score situation, Face++ detector enjoys a great performance margin over other detectors.Click here to get more.

Face++ delivers the leading face techs to global developers. It’s our pleasure to have your witness of improvements of Face++. Stay focus!

Face++ in ICCV2013 (Ⅱ)


Face++ researchers have just returned from ICCV 2013, Sydney. It was an exciting adventure for the team!

During the conference, demos exhibited by Face++ received tremendous attention from both the academic and industrial community. Face++ team had a lot of interesting discussions with the researchers on how to help advance face technology from industry side. Moreover, many professionals with computer vision background showed great interest in applying Face++ service into their own products and applications.

Another piece of good news is that Face++ team won the "300-Face in the Wild" challenge during the workshop on Dec 7. This is the first facial landmark detection challenge in the "wild" scenario, targeting to motivate the progress in this direction. By leveraging the recently developed "deep learning" technology, Face++ team successfully proposed a coarse-to-fine framework for the problem, which has a great advantage over traditional shape-model based methods. This technology is expected to be released on the cloud platform soon! 

"New logo, new service". Face++ team continues to provide leading face technology service to the community, and works closely with developers to apply those technologies into new problems and areas. Keep in touch with us and glad to hear from you!

Update Released: 83 key points for one face!


Hello, Face++ developers. We are pleased to announce that some new features have been released in the latest version API. The Dev Center is also improved in some aspects. New features provided by latest API

  1. A new local face detector has been released (iOS & Android). Developers can download it on the “My App” page. Please refer to Application Management System & Command Line Tool for detailed instructions.
  2.  A new /detection/landmark API is provided. It is able to detect 83 key facial points, including eyebrows, eyes, nose, mouth, and face contour. We hope that it will be a powerful tool for developers to build up interesting interactive applications. Developers can find more details in /detection/landmark.
  3.  A newer version of race analysis algorithm is released. This upgrade reduces the error rate by 50% in our benchmark testing. We will continue to upgrade the back-end API to provide more accurate results for all the face attributes.
Improvements on the website
  1. An overview page of Face++ API is added. It collects all the API interface documents so that developers can quickly locate the information they need.
  2.  “Quick Start” page is reorganized; with step-by-step instructs elaborated to help the fresh users to utilize the advanced face recognition technologies provided by Face++.
  3.  A roadmap for creating new Face++ Apps is added in the Dev Center. Developers can just follow the steps to create their first Face++ App.

Important Update Released: No more fee! More functions!


Face++ announces that all online API are FREE from now! Developers can call the API as many time as you want! Detailed new policies are,

  1. No fee for online API.
  2. No limit on times of API request.
  3. To prevent evil attack, the number of synchronized API requests will be limited. That is, suppose the number of synchronized API requests is k, then at any time, Face++ server will only process no more than k request from one application. For trial version, k=1. For development version, k=3. For online version, there is no limit on k. Applications created before Oct 16, 2013 are all online version by default (but evil usage will be degraded).
In the latest released version, more functions are added. They are,
  1. New attribute in /detection/detect API:
    • landmark (25 key points for one face)
    • glass (whether the person wear a pair of glass or not)
    • smile (whether the person is smiling or not)
    • pose (the 3D orientation of a face, including Pitch/Roll/Yaw)
  2. Update algorithm for /recognition/search and /train/search: We implemented a new algorithm with better performance for face search. You can call /train/search first and then call /recognition/search to have a try with the new algorithm.

Update:Grouping API and Premium Service is launched, and more!


Grouping of photos by similarity of faces is one of the key features of many photo/album related applications. Based on feedback from many of you, we are pleased to announce Grouping API support. Uses and comments are welcomed! For more information on Grouping API, please visit here.

As more and more developersare joining our parade, Face++ API service matures. After careful review and revision of service policy, all of the current service will continue under a new umbrella called “Face++ Community API Service”, while a new service oriented towards business use of larger scale is provided as “Face++ Premium API Service”. For more information, please visit here.

Apart from above, following release of python, Java, iOS SDKs, Ruby SDK comes up, plus a developer-contributed C# SDK. Buaaparty, thanks!.

Last but not least, we are pleased to announce full HTTPs support added to our API services, while the older way of calling us continue to be supported.
