Abstract: A terminal device activates a camera function according to a user manipulation to capture an offline product image of an offline product and transmits the offline product image to a product information providing server to request online product sales information. The terminal device receives the online product sales information from product information providing server, and outputs the online product sales information with the offline product image in the augmented reality. The product information providing server receives the offline product image from the terminal device, and extracts offline product information by analyzing the received offline product image. The server searches the online product sales information corresponding to the extracted offline product information from an electronic commerce server, and provides the online product sales information to the terminal device.

Abstract: An image classifying apparatus may include a database constructor which constructs database by detecting face region from received classification target image, extracting face feature descriptor from detected face region, extracting a costume feature descriptor using position information of detected face region, and storing face feature descriptor and costume feature descriptor in database, a first processor which generates representative image model by comparing face feature descriptor and costume feature descriptor of classification target image stored in database based on a received representative image to search for a similar image and registering similar image in a representative image model for each person, and second processor which compares additional information of representative image stored in representative image model for each person and additional information of classification target image stored in database and classifies image for each person based on similarity measured by adding up weights c
