What is face detection ?
Face detection is a computer technology used to identify human faces in digital images. To make it simpler, it’s like a computer recognizing that the image contains a human.
In face analysis, face detection helps identify which parts of an image or video should be focused on to determine age, gender and emotions using facial expressions. The information gathered will then be used in some applications in many fields for example:
A webcam can be integrated into a television and detect any face that walks by. Once the information is collected, a series of advertisements can be played that is specific toward the detected race/gender/age. An example of such a system is OptimEyes and is integrated into the Amscreen digital signage system.
Facial motion capture:
What is facial motion capture ?
Facial motion capture is the process of electronically converting the movements of a person’s face into a digital database using cameras or laser scanners. This database may then be used to produce computer graphics (CG), computer animation for movies, games, or real-time avatars. Because the motion of CG characters is derived from the movements of real people, it results in a more realistic and nuanced computer character animation than if the animation were created manually.
Facial recognition system:
A facial recognition system is a technology capable of matching a human face from a digital image or a video frame against a database of faces, typically employed to authenticate users through ID verification services, works by pinpointing and measuring facial features from a given image. example:
Founded in 2013, Looksery went on to raise money for its face modification app on Kickstarter. After successful crowdfunding, Looksery launched in October 2014. The application allows video chat with others through a special filter for faces that modifies the look of users. Image augmenting applications already on the market, such as Facetune and Perfect365, were limited to static images, whereas Looksery allowed augmented reality to live videos. In late 2015 SnapChat purchased Looksery, which would then become its landmark lenses function. Snapchat filter applications use face detection technology and on the basis of the facial features identified in an image a 3D mesh mask is layered over the face.
TikTok’s algorithm has been regarded as especially effective, but many were left to wonder at the exact programming that caused the app to be so effective in guessing the user’s desired content. In June 2020, Tiktok released a statement regarding the “For You” page, and how they recommended videos to users, which did not include facial recognition. In February 2021, however, Tiktok agreed to a $92 million settlement to a US lawsuit which alleged that the app had used facial recognition in both user videos and its algorithm to identify age, gender and ethnicity.
In the end we can’t really know if the face detection is good for the human being even though it’s sometimes used to steal our own information to be used against us.
