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 eye-catchability of a document, comprising:
(a) measuring information lightness of the document; and
(b) quantizing the measured information lightness of the document, wherein measuring the information lightness of the document comprises:
measuring a text information amount of the document;
measuring a graphic information amount of the document;
measuring a pictorial information amount of the document; and
wherein measuring the text information amount of the document includes measuring a number of words in the document.
2. The method as claimed in claim 1 , wherein measuring the text information amount of the document includes measuring a number of characters in the document.
3. The method as claimed in claim 2 , wherein measuring the graphic information amount of the document includes measuring a number of primitive graphical constructs used to build the figures.
4. The method as claimed in claim 2 , wherein measuring the pictorial information amount of the document includes summing variances of pixel values from neighborhood pixel values within a pictorial object and dividing by an area of the pictorial object.
5. The method as claimed in claim 1 , wherein measuring the graphic information amount of the document includes measuring a number of primitive graphical constructs used to build the figures.
6. The method as claimed in claim 1 , wherein measuring the pictorial information amount of the document includes summing variances of pixel values from neighborhood pixel values within a pictorial object and dividing by an area of the pictorial object.
7. A method for quantifying a measure of eye-catchability of a document, comprising:
(a) measuring information lightness of the document; and
(b) quantizing the measured information lightness of the document, wherein measuring the information lightness of the document comprises:
measuring a text information amount of the document;
measuring a graphic information amount of the document; and
measuring a pictorial information amount of the document, and
wherein the quantized information lightness of the document is equal to A D /(N T +aN G +bN P ), where A D is an area of the document, N T is the measured text information amount of the document, N G is the measured graphic information amount of the document, N P is the measured pictorial information amount of the document, and a and b are predetermined scaling values.
8. The method as claimed in claim 7 , wherein measuring the graphic information amount of the document includes measuring a number of primitive graphical constructs used to build the figures.
9. The method as claimed in claim 7 , wherein measuring the pictorial information amount of the document includes summing variances of pixel values from neighborhood pixel values within a pictorial object and dividing by an area of the pictorial object.
