<h2 id="technologies">Technologies</h2> <h3>Face Track<a class="footnote-ref" id="fnref:1" href="#fn:1"><sup>1</sup></a></h3> <p>Face Track tracks 3D head poses, facial features, and eyes/gaze for multiple faces in a <a href="/facts/Camera/j4uqsfJQ">camera</a> stream or from a <a href="/facts/Video/F1AV8ben">video</a> file. Face Track has configurable packages that include: facial tracking, <a href="/facts/Face_detection/KVIvPRFA">face and facial landmarks/features detection</a>, <a href="/facts/Head_tracking/vy5ab34S">head tracking</a>, and eye tracking. </p> <h3>Face Analysis<a class="footnote-ref" id="fnref:2" href="#fn:2"><sup>2</sup></a></h3> <p>Face Analysis includes machine learning <a href="/facts/Algorithms/fnl5NmRt">algorithms</a> to determine <a href="/facts/Gender/LfjRHcJy">gender</a>, <a href="/facts/Emotion_recognition/yWGzqfhz">emotions</a> and age. Face Analysis is compatible with Face Track to find/track faces in images or video, determine gender, emotions, and age for a specified face. </p> <h3>Face Recognition<a class="footnote-ref" id="fnref:3" href="#fn:3"><sup>3</sup></a></h3> <p>Face Recognition is used to identify or verify a person from a digital image or a video source using a pre-stored facial data. Visage SDK's <a href="/facts/Face_recognition/mtVxaDln">face recognition</a> algorithms can measure similarities between people and recognize a person’s identity from a frontal facial image by comparing it to pre-stored faces. </p> <h2 id="history-and-application">History and application</h2> <p>The development of Visage SDK began in 2002 when <a href="/facts/Visage_Technologies_AB/fh7MHjhf">Visage Technologies AB</a> was founded in <a href="/facts/Link%C3%B6ping/lfXoRVhy">Linköping</a>, Sweden.
