Scene classification for place recognition
Abstract:
Aspects of the invention pertain to identifying whether or not an image from a user's device is of a place. Before undertaking time and resource consuming analysis of an image using specialized image analysis modules, pre-filtering classification is conducted based on image data and metadata associated with the image. The metadata may include geolocation information. One classification procedure analyzes the metadata to perform a high level determination as to whether the image is of a place. If the results indicate that it is of a place, then a further classification procedure may be performed, where the image information is analyzed, with or without the metadata. This process may be done concurrently with a place match filtering procedure. The results of the further classification will either find a match with a given place or not. The output is a place match either with or without geolocation information.
