Abstract

Identifying at least one object in data for photographed images includes detecting a reference pattern in the data, locating the reference pattern in a table of patterns, and identifying the at least one object according to the reference pattern. The pattern may be located on the at least one object. The at least one object may be a greeting card. The pattern may categorize the greeting card by season and/or occasion. The pattern may identify a sender of the greeting card. The pattern may be provided on an item that is separate from the at least one object. The table of patterns may include a record for at least some of the patterns and the record may include additional information associated with the pattern. The additional information may include tasks that are performed in connection with the pattern. The additional information may include geometric and color parameters of the pattern.

First claim

What is claimed is:

1. A method for identifying additional information associated with a greeting card in a photographed image that includes the greeting card, comprising:
detecting a reference pattern printed on a surface of the greeting card;
locating the reference pattern in a table of patterns; and
determining the additional information according to the reference pattern, wherein the reference pattern identifies a sender of the greeting card.

2. A method, according to claim 1 , wherein the reference pattern categorizes the greeting card by occasion.

3. A method, according to claim 1 , wherein the additional information includes tasks that are performed in connection with the reference pattern.

4. A method, according to claim 3 , wherein a task causes the data to be at least one of: tagged and filed according to the reference pattern.

5. A method, according to claim 1 , wherein the additional information includes geometric and color parameters of the reference pattern.

6. A method for identifying information associated with data for a photographed image, comprising:
detecting a reference pattern printed on a surface of an object in the image by examining the data, wherein the data corresponds to a business card and a business card holder;
locating the reference pattern in a table of patterns;
determining that the object is a business card holder according to the reference pattern; and
determining business card information from the data in response to determining that the object is a business card holder.

7. A method, according to claim 6 , wherein tasks associated with business cards include tasks for correcting orientation of the business card, tasks for performing OCR on the business card to determine a name and contact information, and tasks for storing the name and contact information.

8. A method, according to claim 6 , wherein a task causes the data to be at least one of:
tagged and filed according to the reference pattern.

9. Computer software, provided in a non-transitory computer-readable medium, that identifies additional information associated with a greeting card in a photographed image that includes the greeting card, the software comprising:
executable code that detects a reference pattern printed on a surface of the greeting card;
executable code that locates the reference pattern in a table of patterns; and
executable code that determines the additional information according to the reference pattern, wherein the reference pattern identifies a sender of the greeting card.

10. Computer software, according to claim 9 , wherein the reference pattern categorizes the greeting card by occasion.

11. Computer software, according to claim 9 , wherein the additional information includes tasks that are performed in connection with the reference pattern.

12. Computer software, according to claim 11 , wherein a task causes the data to be at least one of: tagged and filed according to the reference pattern.

13. Computer software, according to claim 9 , wherein the additional information includes geometric and color parameters of the reference pattern.

14. Computer software, according to claim 9 , wherein the software is one of: pre-loaded with a device, installed from an app store, and downloaded from a location of a network operator.

15. Computer software, provided in a non-transitory computer-readable medium, that identifies information associated with data for a photographed image, the software comprising:
executable code that detects a reference pattern printed on a surface of an object in the image by examining the data, wherein the data corresponds to a business card and a business card holder;
executable code that locates the reference pattern in a table of patterns;
executable code that determines that the object is a business card holder according to the reference pattern; and
executable code that determines business card information from the data in response to determining that the object is a business card holder.

16. Computer software, according to claim 15 , wherein tasks associated with business cards include tasks for correcting orientation of the business card, tasks for performing OCR on the business card to determine a name and contact information, and tasks for storing the name and contact information.

17. Computer software, according to claim 15 , wherein a task causes the data to be at least one of: tagged and filed according to the reference pattern.
