Products (e.g., books) often include a significant amount of informative textual information that can be used in identifying the item. An input query image is a photo (e.g., a picture taken using a mobile phone) of a product. The photo is taken from an arbitrary angle and orientation, and includes an arbitrary background (e.g., a background with significant clutter). From the query image, the identification server retrieves the corresponding clean catalog image from a database. For example, the database may be a product database having a name of the product, image of the product, price of the product, sales history for the product, or any suitable combination thereof. The retrieval is performed by both matching the image with the images in the database and matching text retrieved from the image with the text in the database. |
