(Spring 2012) Camera Distractors and Facial Recognition

The document summarizes a study that analyzed existing camera distractors and ways to improve facial recognition security in real-world situations. The researchers conducted experiments to test how people respond to different distractors near security cameras, such as noise, television screens, and privacy concerns. The results suggest that sustained noise is more distracting than instant sounds, and that people are more likely to look away from cameras entering private information. The researchers also optimized camera placements to better capture faces for security purposes.
(Spring 2012) Camera Distractors and Facial Recognition
- 1. Camera Distractors and Facial Recognition Travis Goodspeed, Edward Huang, Bryan Kao, Curtis Bressert, Michael Brockly, Stephen Elliott The purpose of this study was to analyze and improve upon existing camera distractors in real-world situations to access the overall quality of, and improve upon, these existing systems. We address the current lack of efficient security in many real-world places and scenarios. In today’s world, higher security is becoming an increasing necessity, and our experiments suggest several possible solutions for more efficient camera placements to better be able to capture peoples’ faces more fully, and for a longer period of time, to enhance the environments and make them more safe, secure, and monitored if need be.

Yet when people are not having to hide anything (passerby’s) they were more likely to look at the camera. Noise Distractor Overall, people are not too distracted by an instantaneous noise (a pan dropping), however when that noise is sustained over a period of time (loud music) people are more prone to looking in that direction in search of what it is that’s catching their attention. ESPN Television We found that people are distracted/take notice when relevant, recent, or newsworthy information is being put in front of them to see/watch/read on a television screen or monitor. 1 2 3 4 For this experiment we focused on optimizing our camera placements to be able to capture both the test subject and the administrator in the same shot. It was important for us to utilize more efficient camera placements in order to capture close ups of each individual station. By doing this, it will enable us to be able to more accurately examine the details of the scenario rather than having the typical “room-wide” camera angles seen in many real- world applications today.
