Difficulties faced in the ELEC301 Viola-Jones-based facial detection and feature recognition project. This module is part of a collection.

Some of the difficulties we face heading in to this project deal mainly with the picture quality. If a person is covered by shadow or if lighting is uneven, the algorithm won’t work properly since it uses differences in light to detect a face. Additionally, if a person’s face is tilted or if part of their face is obstructed by an object detection will not take place. Movement such as turning or blinking is also an issue.
