Deception detection is a relevant ability in high stakes situations such as police interrogatories or court trials, where the outcome is highly influenced by the interviewed person behavior. With the use of specific devices, e.g. polygraph or magnetic resonance, the subject is aware of being monitored and can change his behavior, thus compromising the interrogation result. For this reason, video analysis-based methods for automatic deception detection are receiving ever increasing interest.

The ability to discern lies, more broadly known as deception detection, is an invaluable skill that can strongly influence the outcome of relevant situations such as court trials and police interrogatories. Several devices currently exist and are being used (e.g., magnetic resonance and polygraphs) to ease those tasks; although, due to the subject awareness of such tools, their effectiveness can be compromised by the person intentional behavioural changes.
