Smiling face identification and encouragement system

Abstract

The invention discloses a smiling face identification and encouragement system, and belongs to the technical field of image processing and artificial intelligence. The smiling face identification and encouragement system is implemented through the following steps: collecting basic expression samples; automatically starting videos at startup; collecting the expressions in real time; pre-processing the expression images; identifying the expression images; carrying out comprehensive statistics, analysis and judgment; summing up the phased expressions; and encouraging the staff to relax. According to the technical key point of the invention, a plurality of expression characteristics represented through vectors are matched with corresponding key characteristics in several pre-shot user typical expression samples to compare the similarity; the difference and geometric shape change between the Euclidean distance at a captured expression key characteristic and the Euclidean distance at a preset typical expression characteristic are judged; and after normalization, a statistic shape analysis method is used for judging whether the expression in the phase is anxiety or happiness according to the expression distribution probability of the staff in a certain time period. The system has the benefit of encouraging the staff to feel anxious less and smile more so as to improve the working efficiency and the living quality.

Description

technical field [0001] The invention belongs to the field of image processing methods and artificial intelligence, uses facial expression collection, analysis, and recognition technologies to remind and help anxious expressions, encourage smiling or calm expressions, and relates to human face image acquisition and detection, human face Image preprocessing, face image feature extraction, face image matching and recognition, comprehensive shape statistical analysis, artificial intelligence and network interaction and other technologies. Background technique [0002] Now employees are under great pressure in work and life, and often unconsciously produce negative expressions such as frowning, nervousness, anxiety, and unhappiness. Such expressions will lead to bad moods for a long time. This negative energy is harmful to health and affects the quality of work and life.
