At least one image captured from a printed document 3203 and at least one image captured from a display surface other than a printed document 3202 are processed. A surface-type-identification module 3204 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 3210 preprocesses the at least one embedded-interaction-code image captured from a display surface other than a printed document 3206. A printed-document-preprocessing module 3212 preprocesses the at least one embedded-interaction-code images captured from a printed document 3206. An embedded-interaction-code-processing module 3214 outputs location information 3216 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.
