Platforms: all

Liveness API exposure
The usage of the Liveness preset actions is now also available through the FaceRecognition license.

Upgrade of VNN algorithm for tracking and detecting masked faces
Face tracking and detection algorithms are enhanced so that they can track and detect faces wearing protective masks of various colors and patterns.

Removal of the legacy tracking and detection algorithm
With the improvement of the quality and performance of the VNN algorithm, we have achieved state-of-the-art face tracking and detection. In order to simplify usage and reduce the data, all those algorithms that are no longer competitive are removed.

Switching from visible to physical contour
Introducing the physical contour the stability and accuracy of one of the main visage|SDK features – 3D head-pose estimation has been improved. Improved the usability of the visage|SDK for many market fields such as DMS, Virtual Try-on, and Gaming.

10 Feb 2020 visage|SDK 8.6.1 (Stable)

A novel experimental tracking algorithm – VNN – introduced

The new algorithm minimizes jitter, increases tracking accuracy and robustness but reduces tracking performance (speed). It is demonstrated in ShowcaseDemo and FaceTracker2 samples via new Ultra tracking configuration.

New neural network runner provided – OpenVINO™ toolkit

Significantly improves the performance of age estimation, face recognition and face tracking with VNN algorithm on Intel 64-bit processors.

OpenVINO is a trademark of Intel Corporation or its subsidiaries.

Ear tracking NEW FEATURE

Additional 24 feature points on ears are now tracked (12 points per ear). Ear tracking is configurable through the tracker configuration file or API.

Iris tracking NEW FEATURE

Face data from tracker and detector now includes information about iris diameter.

VisageConfiguration API introduced

It is now possible to modify specific tracker configuration parameters via an interface during tracking.

Age estimation accuracy improved

30 Mar 2019 visage|SDK 8.5 (Stable)

Improved smoothing filter

Smoothing of feature points is performed using multiple filters. For still face, higher amount of smoothing is applied while fast movements are less smoothed in order to avoid noticeable delay. Increased stability of feature points and head position especially in profile and half-profile pose.

Refactoring of frame preprocessing resulting in more stable FPS and improved accuracy on high-resolution frames

The core tracking loop was re-implemented to make the tracking frame rate less dependent on the size of the face in the image. This fixes performance drops in cases where the face takes up a small portion of the frame. Additionally, noise introduced by resizing of higher-resolution frames is reduced which results in more stable tracking.

HTML5 API upgraded to use typed arrays

API for fetching tracking data has been modified to return typed arrays. Improves performance and simplifies memory management of tracked data.

IOS ANDROID ShowcaseDemo introduces example of tracking from video including source code.
