Real time image recognition of facial features for detecting a true breath

TL;DRAbstract

The effects of driving under the influence of alcohol can be severe. In an effort to reduce the number of drunk drivers, alcolocks have been deployed. However, if a driver tries to cheat the system and succeeds, the effects may cause severe damage to both humans and property. One way of beating the system is by fooling the breathalyzer that the breath produced doesn’t contain alcohol. This is usually done using a device which either filters a breath, or by having a device that blows clean air into the alcolock. In this paper the problem of if it’s possible to determine whether a true breath is made by using facial and feature detection, is answered. A true breath is an unobstructed, real breath from a person. True breath identification can be used in order to, for example, determine if a mouthpiece-less alcolock device is being used correctly. To solve this problem facial and feature detection was used. In order to find the best methods for facial and feature detection, research result
