An image-based outdoor place recognition and information retrieval system

In image-based place recognition, an image is used to deduce the location of the viewer during image acquisition. The identified place can subsequently be used to provide additional information to the user. This demonstration paper briefly describes a system that performs image-based place recognition on outdoor images, made possible by viewer-centric data sampling and local feature-based scene identification. It also explains our proposed demonstration that displays the recognized place on a map and provides information of amenities in its vicinity.
