Mobile Image Recognition: Architectures and Tradeoffs

Free registration required

Executive Summary

The authors argue that the most desirable architecture for mobile image recognition runs the complete algorithm on the mobile device. Alternative solutions that run the recognizer on a remote server will not be as desirable because of the delay between image capture and receipt of a result that can cause users to abandon the technique. They present a method for mobile recognition of paper documents and an application to newspapers that lets readers retrieve electronic data linked to articles, photos, and advertisements. They show that the index for a reasonable collection of daily newspapers can be downloaded in less than a minute and will fit in the memory of today's mid-range smart phones.
