Searching in clutter: The effect of feature congestion in leaf litter
Becky Maguire, Postgraduate Researcher, University of St Andrews
Zoom
Abstract
In nature, predators encounter cluttered scenes on a regular basis. This may affect their ability to successfully hunt for prey, camouflaged or not. Since natural visual clutter is often complex, with many different objects and continuous textures present, it can be difficult to measure or define ‘clutter’. In turn, this makes it difficult to measure how clutter affects predator behaviour when searching for prey.
In recent years, various computational models to measure visual clutter have been proposed. This talk will focus on how well a particular clutter model, Rozenholtz’s Feature Congestion model, predicts human ability to find a target on an artificial leaf litter background.
Biography
Becky graduated with a BSc in Experimental Psychology from the University of Bristol in 2015. During her undergraduate studies, she became interested in animal camouflage, so continued within the same department to complete an MRes focused on disruptive camouflage in 2018. The same year, she moved to sunny Scotland to begin a PhD at the University of St Andrews, focusing on the effect of predator attention on foraging ability.
