The co-occurrence of objects in visual scenes reflects the semantic structure of the world: cups are more likely to appearin scenes with tables than airplanes, for example. Both human and machine vision use these co-occurrences to supportrecognition of individual objects. A reasonable assumption is that these co-occurrences are ubiquitous and present forall perceivers. However, the scenes observed by infants are highly dependent on their body postures and locations, bothof which change dramatically over the first year of post-natal life. To measure these changing co-occurrences in infant-perspective scenes, we collected images from infants wearing head cameras in everyday home environments comparingthree age groups: 1-3, 6-8 and 11-12 months. Using graph theoretical analysis, we conclude that the semantic structure ofscenes in 6-8 months differs from whats in younger and older infants.
