Street Perception Evaluation Considering Socioeconomics (SPECS)

Repository for the Street Perception Evaluation Considering Socioeconomics (SPECS) dataset developed in the It's not you, it's me: Global urban visual perception varies across demographics and personalities project.

This dataset is also used in related work titled It is not always greener on the other side: Greenery perception across demographics and personalities in multiple cities, codebase and additional dataset is also available.

These projects were developed at the Future Cities Lab Global in the Singapore-ETH Centre in close collaboration with the Urban Analytics Lab (UAL) at the National University of Singapore (NUS).
