View-matching and image-matching

One of the significant contributions that studies of insect navigation can make to the wider field of comparative cognition is to suggest parsimonious mechanisms that might underpin spatial behaviour. One such mechanism is the use of egocentric views, which has been put forward recently as an alternative explanation to the presumed extraction of environmental geometry by vertebrates. In this article, we highlight how this debate (views vs geometry) can only be fruitful if we have a good sense of what information is available in an animal’s view. As an analytical shorthand, image matching is often used, however the important thing to remember is that animal’s views of the world will be filtered, processed and actively generated by movement therefore not always similar to a raw image. Understanding the information available in a view is essential before we can discard the use of egocentric views within a given experiment. For instance, the ability of vertebrates to obtain distance information and to use 3D views for navigation can be achieved egocentrically and included in view-based matching, even though it cannot not accounted by image-matching models.
