Can you recognise emotions through facial expressions?

We can classify all human emotions into two main groups: Positive (Happiness, Excitement and Tenderness) or Negative (Anger, Sadness and Fear). As part of the BIGMATH subproject in the application field of Human Face Reconstruction, our PhD students Stevo Racković and Rongjiao Ji released a website presenting a video with facial expressions: would you like to estimate in which groups these expressions can be classified? The video has been realised in cooperation with the BIGMATH industrial partner 3Lateral.
