Recognize items depicted as images

摘要

Products (e.g., books) contain a significant amount of useful document information that can be used to identify an item. The input query image is a picture of the product (for example, a picture taken using a mobile phone). Photographs are taken at any angle and direction and include any background (e.g., background with significant clutter). From the query image, the identification server retrieves the corresponding clean catalog image from the database. For example, the database may be a product database having product names, product images, product prices, product sales histories, or any suitable combination thereof. The search is performed by both matching the image in the database with the image and matching the text in the database with the text retrieved from the image.
