Patterns of saliency and semantic features distinguish gaze of expert and novice viewers of surveillance footage.

ABSTRACT: When viewing the actions of others, we not only see patterns of body movements, but we also "see" the intentions and social relations of people.

Low-level image features were extracted by a visual salienc
