Embedded interaction code enabled surface type identification
First Claim
1. A system that processes at least one image captured from a printed document and that processes at least one image captured from a display surface other than a printed document, the system comprising:
- a surface-type-identification module that accepts as input 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 and that identifies, for a particular image, the type of surface from which the image was captured, wherein the type of surface is selected from the group consisting of;
a printed document and a display surface other than a printed document;
a display-surface-preprocessing module that preprocesses the at least one embedded-interaction-code image captured from a display surface other than a printed document;
a printed-document-preprocessing module that preprocesses the at least one embedded-interaction-code images captured from a printed document; and
an embedded-interaction-code-processing module that 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.

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.

9. A computer-readable medium having computer-executable instructions for performing steps comprising:
-
generating a feature vector that specifies how even the gray level distribution is for an image that includes embedded-interaction-code information and that was captured from at least one of a printed document and a display surface other than a printed document; and
using the feature vector to identify the surface type from which the image was captured. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A computer-readable medium having computer-executable instructions for performing steps comprising:
-
using a LaPlacian operator to generate a filtered image by filtering an image that includes embedded-interaction-code information and that was captured from at least one of a printed document and a display surface other than a printed document; and
using the filtered image to identify the surface type from which the image was captured. - View Dependent Claims (17, 18, 19, 20)
