Segregation of handwritten information from typographic information on a document
First Claim
1. A method of segregating handwritten information from typographic information on a document, the method comprising:
- receiving an electronic document image of a document, the electronic document image comprising a plurality of pixels, wherein each of the plurality of pixels comprises a characteristic of a plurality of characteristics;
identifying a first, a second and a third most frequently occurring characteristic of the plurality of pixels, wherein the pixels of the plurality of pixels comprising the first most frequently occurring characteristic of the plurality of characteristics represent a background of the document;
determining typographic information of the document, wherein the typographic information is represented by the pixels of the plurality of pixels of the electronic document image which comprise the second most frequently occurring characteristic of the plurality of characteristics;
determining, by a processor, handwritten information of the document, wherein the handwritten information is represented by the pixels of the plurality of pixels of the electronic document image which comprise the third most frequently occurring characteristic of the plurality of characteristics; and
deriving a first representation of the handwritten information and a second representation of the typographic information.

Abstract
A system for segregating handwritten information from typographic information on a document may include a memory, an interface, and a processor. The memory stores an electronic document image of a document where the electronic document image includes pixels and each pixel has a characteristic. The processor may receive, via the interface, the electronic document image and may identify first, second and third most frequently occurring characteristics of the pixels of the electronic document image. The pixels having the first most frequently occurring characteristic represent a background of the document. The processor may determine the typographic information of the document as represented by pixels having the second most frequently occurring characteristic. The processor may determine the handwritten information of the document as represented by pixels having the third most frequently occurring characteristic. The processor may derive a first representation of the handwritten information and a second representation of the typographic information.

16. A method of segregating handwritten information from typographic information on a document, the method comprising:
-
receiving an electronic document image of a document, the electronic document image comprising a plurality of pixels, wherein each of the plurality of pixels comprises a characteristic of a plurality of characteristics; determining a document type of the electronic document image, wherein the document type is indicative of a first characteristic of the plurality of pixels associated with typographic information and a second characteristic of the plurality of pixels associated with handwritten information; determining typographic information of the document, wherein the typographic information is represented by the pixels of the plurality of pixels of the electronic document image which comprise the first characteristic; determining, by a processor, handwritten information of the document, wherein the handwritten information is represented by the pixels of the plurality of pixels of the electronic document image which comprise the second characteristic; and deriving, based on frequency of occurrence, a representation of the handwritten information and the typographic information.

17. A method of separating a first information applied to a medium at a first date/time from a second information applied to the medium at a second date/time, the method comprising:
-
receiving an electronic image of a medium, the medium comprising a first information applied at a first date/time and a second information applied at a second date/time, wherein the electronic image comprises a plurality of pixels and each pixel of the plurality of pixels comprises a characteristic of a plurality of characteristics; determining the first information applied to the medium, wherein the first information applied to the medium comprises the pixels of the plurality of pixels of the electronic image which comprise a second most frequently occurring characteristic of the plurality of characteristics; determining, by a processor, the second information applied to the medium, wherein the second information applied to the medium comprises pixels of the plurality of pixels of the electronic image which comprise a third most frequently occurring characteristic of the plurality of characteristics; and deriving a first representation of the first information and a second representation of the second information. - View Dependent Claims (18, 19)

20. A system for segregating handwritten information from typographic information on a document, the system comprising:
-
a memory operative to store an electronic document image of a document, the electronic document image comprising a plurality of pixels, wherein each of the plurality of pixels comprises a characteristic of a plurality of characteristics; an interface coupled with the memory and operative to receive the electronic document image; and a processor coupled with the interface and operative to receive, via the interface, the electronic document image of the document, identify a first, a second, and a third most frequently occurring characteristic of the plurality of pixels, wherein the pixels of the plurality of pixels comprising the first most frequently occurring characteristic of the plurality of characteristics represent a background of the document, determine typographic information of the document, wherein the typographic information is represented by the pixels of the plurality of pixels of the electronic document image which comprise the second most frequently occurring characteristic of the plurality of characteristics, determine handwritten information of the document, wherein the handwritten information is represented by the pixels of the plurality of pixels of the electronic document image which comprise the third most frequently occurring characteristic of the plurality of characteristics, and derive a first representation of the handwritten information and a second representation of the typographic information. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31)
