Scene classification for place recognition
First Claim
1. A method of classifying an image, comprising:
- receiving an image and metadata of the image from a user device;
performing a first classification of the image using only the metadata to determine whether the image is a place;
performing a second classification of the image using both the metadata and information about the image to determine whether the image is the place; and
when either the first or second classification determines that the image is of the place, then preparing place information for presentation by the user device;
wherein if different filter modules identify the image as being of different types, then the first and second classifications are used to select which filter module identification is correct.

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.

14. An apparatus for classifying an image, the apparatus comprising:
-
means for communicating with a mobile user device; and at least one processor coupled to the communicating means, the at least one processor configured to; receive an image and metadata of the image from a user device; perform a first classification of the image using only the metadata to determine whether the image is a place; perform a second classification of the image using both the metadata and information about the image to determine whether the image is the place; and when either the first or second classification determines that the image is of the place, then prepare place information for presentation by the user device; wherein if different filter modules identify the image as being of different types, then the first and second classifications are used to select which filter module identification is correct. - View Dependent Claims (15, 16, 17, 18, 19, 20)
