System, method, and computer program product for determining whether text within an image includes unwanted data, utilizing a matrix
View Patent ↗A system, method, and computer program product are provided for determining whether text within an image includes unwanted data, utilizing a matrix. In operation, a matrix corresponding to an image is generated. Additionally, text within the image is identified utilizing the matrix. Furthermore, it is determined whether the text includes unwanted data.
1. A method to be performed in conjunction with a processor operating in an electronic environment, comprising:
parsing a plurality of pixels of an image;
identifying a property associated with a predetermined portion of the plurality of pixels;
determining whether each pixel of the plurality of pixels includes the property;
entering a predetermined value for each of the plurality of pixels in a matrix at a location corresponding to the pixel, wherein the predetermined value is based upon whether the pixel includes the property;
identifying text within the image, utilizing the matrix; and
determining whether the text includes unwanted data.
2. The method of claim 1 , wherein the property is a background property of the image.
3. The method of claim 1 , wherein the predetermined portion is a majority of the plurality of pixels.
4. The method of claim 1 , wherein the plurality of pixels include all of the pixels of the image.
5. The method of claim 1 , wherein a dimension of the matrix is a function of a resolution of the image.
6. The method of claim 1 , wherein entering the predetermined value includes:
entering a first predetermined value if the pixel includes the property; and
entering a second predetermined value if the pixel includes does not include the property.
7. The method of claim 6 , wherein the first predetermined value is representative of the pixel corresponding to a background of the image.
8. The method of claim 6 , wherein the second predetermined value is representative of the pixel corresponding to a character of the image.
9. The method of claim 6 , wherein identifying the text within the image includes identifying a maximum height of entries in the matrix having the second predetermined value.
10. The method of claim 6 , wherein identifying the text within the image includes identifying contiguous entries in the matrix having the second predetermined value.
11. The method of claim 10 , wherein the text is identified by comparing the contiguous entries with predefined patterns representative of text.
12. The method of claim 10 , wherein identifying the text further includes identifying the contiguous entries as a sub-matrix.
13. The method of claim 12 , wherein identifying the text further includes comparing the sub-matrix to at least one predefined matrix associated with text.
14. The method of claim 1 , wherein the text is determined to include unwanted data, based on a comparison of the text with predefined text known to be unwanted.
15. The method of claim 1 , wherein the image is received from an electronic message.
16. The method of claim 1 , wherein the unwanted data includes an unsolicited electronic message.
17. The method of claim 16 , wherein the unsolicited electronic message includes an advertisement.
18. The method of claim 1 , further comprising reacting if it is determined that the text includes the unwanted data.
19. The method of claim 18 , wherein the reacting includes at least one of deleting, quarantining, categorizing, and reporting the unwanted data.
20. A computer program product embodied on a non-transitory medium for performing operations, comprising:
parsing a plurality of pixels of an image;
identifying a property associated with a predetermined portion of the plurality of pixels;
determining whether each pixel of the plurality of pixels includes the property;
entering a first predetermined value for each of the plurality of pixels in a matrix at a location corresponding to the pixel if the pixel includes the property;
entering a second predetermined value for each of the plurality of pixels in the matrix at a location corresponding to the pixel if the pixel includes does not include the property;
identifying text within the image, utilizing the matrix; and
determining whether the text includes unwanted data.
21. A system, comprising:
a processor configured for performing the operations of:
parsing a plurality of pixels of an image;
identifying a property associated with a predetermined portion of the plurality of pixels;
determining whether each pixel of the plurality of pixels includes the property;
entering a first predetermined value for each of the plurality of pixels in a matrix at a location corresponding to the pixel if the pixel includes the property;
entering a second predetermined value for each of the plurality of pixels in the matrix at a location corresponding to the pixel if the pixel includes does not include the property;
identifying text within the image, utilizing the matrix; and
determining whether the text includes unwanted data.
22. The system of claim 21 , wherein the processor is coupled to memory via a bus.
