Spatial frequencies for the visual processing of the facial expression of pain

Conclusion Our results : • Highlight the importance of the mid-SFs in the visual processing of the facial expression of pain. • Show that any method removing mid-SFs offers an incomplete account of SFs diagnosticity. However, our classification vectors show that more diagnostic SFs are present < 8 cpf than > 32 cpf thus replicating Wang and coll (2015; 2017).
