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 colorfulness of objects in the document, measuring the colorfulness of objects in the document includes measuring a saturation value for the object; and
(b) quantizing the measured colorfulness of an object on a page in the document wherein the quantized colorfulness of an object in the document is a product of the measured saturation value and an area of the object divided by an area of the page.
2. The method as claimed in claim 1 , wherein measuring the colorfulness of objects in the document includes measuring a chrominance value for the object.
3. The method as claimed in claim 2 , wherein the quantized colorfulness of an object in the document is a product of the measured chrominance value and an area of the object divided by an area of the page.
4. The method as claimed in claim 1 , wherein the saturation value equals max(R, G, B)−min(R, G, B), where R, G, and B are color values in RGB colorspace.
5. The method as claimed in claim 1 , wherein the saturation value equals [E 2 +S 2 ] 1/2 where E=R−G, S=((R+G)/2)−B, and R, G, and B are color values in RGB colorspace.
6. A method for quantifying a measure of quality of a document, comprising:
(a) measuring a colorfulness of a document, measuring the colorfulness of the document includes measuring a saturation value for each object in the document; and
(b) quantizing the measured colorfulness of the document, wherein the quantized colorfulness of the document is a sum of a product of each measured saturation value and an area of the corresponding object divided by an area of the document.
7. The method as claimed in claim 6 , wherein measuring the colorfulness of the document includes measuring a chrominance value for each object in the document.
8. The method as claimed in claim 7 , wherein the quantized colorfulness of the document is a sum of a product of each measured chrominance value and an area of the corresponding object divided by an area of the document.
9. The method as claimed in claim 6 , wherein each saturation value equals max(R, G, B)−mm(R, G, B), where R, B, and B are color values for an object in RGB colorspace.
10. The method as claimed in claim 6 , wherein each saturation value equals [E 2 +S 2 ] 1/2 where E=R−G, S=((R+G)/2)−B, and R, G, and B are color values for an object in RGB colorspace.
