“In the field of micro expression recognition, this study proposes a multi attention dual stream network method based on color and optical flow, which effectively improves recognition accuracy. By extracting facial emotional and physiological features through CIE Luv color difference map, combined with dual attention module and cross attention mechanism, accurate classification of micro expressions has been achieved. The experimental results on the SAMM and CASME II datasets are superior to mainstream algorithms, providing a new solution for micro expression recognition research.”
