A New Feature Extraction and Recognition Method for Microexpression Based on Local Non-negative Matrix Factorization

Microexpression is usually characterized by short duration and small action range, and the existing general expression recognition algorithms do not work well for microexpression. As a feature extraction method, non-negative matrix factorization can decompose the original data into different compone...
