Method for measuring and quantizing document quality
View Patent ↗Text, images, and/or graphics of electronic documents should be organized and laid out in a two-dimensional format for presentation to the viewer. The best such layout depends upon the content present, the creator's intent, the output device, and the viewer's interests. To analyze the qualitative nature of the layout in quantifiable terms, the electronic document is measure using various quantifiable factors; such as, balance, uniformity, white space management, alignment, consistency, legibility, etc.; that impact a qualitative nature of a document. Such quantifiable factors are then used to quantize the aesthetics, ease of use, eye-catching ability, interest, communicability, comfort, and convenience of the document.
1. A method for quantifying a measure of quality of a document, comprising:
(a) measuring a white space fraction of objects in the document; and
(b) quantizing the measured white space fraction of objects in the document, and
(c) determining that the quantized white space fraction of objects in the document is an undesirable amount when the quantized white space fraction is greater than a predetermined value.
2. The method as claimed in claim 1 , wherein the quantized white space fraction of objects in the document is an amount of area not associated with objects in the document.
3. The method as claimed in claim 1 , further comprising:
(c) determining that the quantized white space fraction of objects in the document is an undesirable amount when the quantized white space fraction is greater than fifty percent of an imageable area of the document.
4. The method as claimed in claim 1 , further comprising:
(c) determining that the quantized white space fraction of objects in the document is an undesirable amount when the quantized white space fraction is less than fifty percent of an imageable area of the document.
5. The method as claimed in claim 1 , further comprising:
(c) determining that the quantized white space fraction of objects in the document is optimal when the quantized white space fraction is equal to about fifty percent of an imageable area of the document.
6. The method as claimed in claim 1 , wherein the quantized white space fraction of objects in the document is equal to 1−4((A O /A P )−0.5) 2 wherein A O is a total object area and A P is a total page area.
7. A method for quantifying a measure of quality of a document, comprising:
(a) measuring trapped white space in the document, measuring the trapped white space in the document comprises measuring an amount of white space connected to an edge of a page of the document and measuring an amount of area associated with an object on the page of the document; and
(b) quantizing the measured trapped white space in the document.
8. The method as claimed in claim 7 , wherein measuring the trapped white space in the document comprises:
measuring, for each page, an amount of white space connected to an edge of an associated page of the document;
measuring, for each page, an amount of area associated with an object on the associated page of the document;
determining a trapped white space value for each page, the trapped white space value being equal to a sum of the measured amount of white space connected to an edge of the associated page of the document and the measured amount of area associated with an object on the associated page of the document, the sum being divided by a total area of the associated page of the document.
9. The method as claimed in claim 8 , wherein the quantized measured trapped white space in the document is equal to an average of the determined trapped white space values.
10. The method as claimed in claim 8 , wherein quantized measured trapped white space in the document is equal to a non-linear combination of the determined trapped white space values.
11. The method as claimed in claim 8 , wherein quantized measured trapped white space in the document is equal to a square root of an average of each determined trapped white space value squared.
12. The method as claimed in claim 8 , wherein quantized measured trapped white space in the document is equal to a Y root of an average of each determined trapped white space value raised to a Y power where Y is equal to or greater than 2.
