Abstract
At least one image captured from a printed document and at least one image captured from a display surface other than a printed document are processed. A surface-type-identification module accepts as input both types of images and identifies, for a particular image, the type of surface from which the image was captured. A display-surface-preprocessing module preprocesses the at least one embedded-interaction-code image captured from a display surface other than a printed document. A printed-document-preprocessing module preprocesses the at least one embedded-interaction-code images captured from a printed document. An embedded-interaction-code-processing module outputs location information for at least one of the at least one image captured from a printed document and the at least one image captured from a display surface other than a printed document.
