Recognizing and processing object and action tags from stickers
Handling data for a photographic image, includes detecting a reference pattern in the data, detecting at least one sticker in the data, determining an action associated with the at least one sticker, and performing the action on the data. The reference pattern may be a uniform grid pattern of dots preprinted on paper. A paper type may be determined according to the reference image. Determining an action associated with the at least one sticker may depend, at least in part, on the paper type. Detecting a particular one of the stickers may cause data for the photographic image to be stored in a particular location. Detecting a particular one of the stickers may cause data for the photographic images to be assigned particular tags used for organizing and searching.
1. A computer-implemented method for a user to perform a particular action on data for a photographic image, comprising:
a user handwriting notes on paper;
the user affixing at least one sticker on the paper;
the user photographing the paper to generate the data for a photographic image;
a processor performing the steps of:
detecting a reference pattern in the data, wherein the reference pattern is pre-printed on the paper and provides parameters for correction of the photographic image and wherein a paper type is determined according to the reference pattern;
detecting at least one sticker in the data;
selecting the particular action from a plurality of possible actions based on the at least one sticker and on the paper type; and
performing the particular action on the data.
2. A computer-implemented method, according to claim 1 , wherein the reference pattern is a uniform grid pattern of dots preprinted on the paper.
3. A computer-implemented method, according to claim 1 , wherein detecting a particular one of the stickers causes data for the photographic image to be stored in a particular location.
4. A computer-implemented method, according to claim 1 , wherein detecting a particular one of the stickers causes data for the photographic images to be assigned particular tags used for organizing and searching.
5. A computer-implemented method, according to claim 1 , wherein a particular one of the stickers represents a custom tag that is assigned after data for the photographic image is stored.
6. A computer-implemented method, according to claim 1 , wherein detecting a particular one of the stickers causes handwritten text corresponding to the sticker to be used for a title of a note corresponding to the data for the photographic image.
7. Computer software, provided in a non-transitory computer-readable medium, that handles data for a photographic image, the software comprising:
executable code that detects a reference pattern in the data, wherein the reference pattern is pre-printed on the paper and provides parameters for correction of the photographic image and wherein the data is provided by a photograph taken by a user of a handwritten note of the user on which the user had affixed a sticker;
executable code that determines a paper type according to the reference pattern;
executable code that detects the at least one sticker in the data;
executable code that determines an action associated with based on the at least one sticker and on the paper type; and
executable code that performs the action on the data.
8. Computer software, according to claim 7 , wherein the reference pattern is a uniform grid pattern of dots preprinted on the paper.
9. Computer software, according to claim 7 , wherein detecting a particular one of the stickers causes data for the photographic image to be stored in a particular location.
10. Computer software, according to claim 7 , wherein detecting a particular one of the stickers causes data for the photographic images to be assigned particular tags used for organizing and searching.
11. Computer software, according to claim 7 , wherein a particular one of the stickers represents a custom tag that is assigned after data for the photographic image is stored.
12. Computer software, according to claim 7 , wherein detecting a particular one of the stickers causes handwritten text corresponding to the sticker to be used for a title of a note corresponding to the data for the photographic image.
13. Computer software, according to claim 7 , wherein the software is one of: pre-loaded with a device, installed from an application store, and downloaded from a location of a network operator.
14. A computer-implemented method, according to claim 1 , wherein the parameters for correction of the photographic image estimate camera view angle to provide perspective correction.
15. A computer-implemented method, according to claim 1 , wherein the parameters for correction of the photographic image are used to estimate a distribution of distances between dots of a uniform grid pattern of dots along a single line augmented by calculating gridline curvature to correct for curved edges of the image.
16. Computer software, according to claim 7 , wherein the parameters for correction of the photographic image estimate camera view angle to provide perspective correction.
17. Computer software, according to claim 7 , wherein the parameters for correction of the photographic image are used to estimate a distribution of distances between dots of a uniform grid pattern of dots along a single line augmented by calculating gridline curvature to correct for curved edges of the image.
