Abstract
[abstFig src='/00280002/14.jpg' width=""280"" text='Similarity map between image sequences' ]Visual recognition of previously visited places is a basic cognitive skill for a wide variety of living beings, including humans. This requires a method to extract relevant cues from visual input and successfully match them to memories of known locations, disregarding environmental variations such as lighting changes, viewer pose differences, moving objects and scene occlusion.Interest point correlationis a visual place recognition method inspired by results from neuroscience and psychology; specifically, it addresses those challenges by converting raw visual inputs to a low-variance representation, selecting regions-of-interest for representation matching, and identifying consistent matching trends. Real-world experiments employing a mobile robot demonstrate that interest point correlation is robust to visual changes, suggesting its founding principles are sound.
