Abstract: Embodiments of this invention relate to detecting and blurring images. In an embodiment, a system detects objects in a photographic image. The system includes an object detector module configured to detect regions of the photographic image that include objects of a particular type at least based on the content of the photographic image. The system further includes a false positive detector module configured to determine whether each region detected by the object detector module includes an object of the particular type at least based on information about the context in which the photographic image was taken.

Abstract: A method and apparatus for enabling dynamic product and vendor identification and the display of relevant purchase information are described herein. According to embodiments of the invention, a recognition process is executed on sensor data captured via a mobile computing device to identify one or more items, and to identify at least one product associated with the one or more items. Product and vendor information for the at least one product is retrieved and displayed via the mobile computing device. In the event a user gesture is detected in response to displaying the product and vendor information data, processing logic may submit a purchase order for the product (e.g., for an online vendor) or contact the vendor (e.g., for an in-store vendor).

Abstract: A gaze tracking technique is implemented with a head mounted gaze tracking device that communicates with a server. The server receives scene images from the head mounted gaze tracking device which captures external scenes viewed by a user wearing the head mounted device. The server also receives gaze direction information from the head mounted gaze tracking device. The gaze direction information indicates where in the external scenes the user was gazing when viewing the external scenes. An image recognition algorithm is executed on the scene images to identify items within the external scenes viewed by the user. A gazing log tracking the identified items viewed by the user is generated.

Abstract: A visual query is received from a client system, along with location information for the client system, and processed by a server system. The server system sends the visual query and the location information to a visual query search system, and receives from the visual query search system enhanced location information based on the visual query and the location information. The server system then sends a search query, including the enhanced location information, to a location-based search system. The search system receives and provides to the client one or more search results to the client system.

Abstract: Systems and methods for selecting interest point descriptors for object recognition. In an embodiment, the present invention estimates performance of local descriptors by (1) receiving a local descriptor relating to an object in a first image; (2) identifying one or more nearest neighbor descriptors relating to one or more images different from the first image, the nearest neighbor descriptors comprising nearest neighbors of the local descriptor; (3) calculating a quality score for the local descriptor based on the number of nearest neighbor descriptors that relate to images showing the object; and (4) determining, on the basis of the quality score, if the local descriptor is effective in identifying the object.
