Embodiment 1

[0069] Please refer to Figure 1 to Figure 3 , Embodiment 1 of the present invention is:

[0070] A method for evaluating the legibility of document texts, comprising:

[0071] S1. Use a common document renderer to render the original document to generate the first picture, and use a preset transparent text document renderer to render all the text on the original document in a transparent manner, keeping the font, font size and typesetting of the text At the same time as the position attribute and remove the pixels of the text itself, a second image is generated;

[0072] In this embodiment, the original document can be a PPT document, an EXCEL form or a WORD document, the common document renderer is the mainstream open source office suite LibreOffice, and the transparent text document renderer is a modification and customization of the open source code;

[0073] S2. Comparing the first picture and the second picture, and calculating the LAB average distance of the differenc...

Embodiment 2

[0097] Please refer to Figure 4 , the second embodiment of the present invention is:

[0098] A terminal 1 for document text legibility evaluation, including a processor 2, a memory 3, and a computer program stored on the memory 3 and operable on the processor 2, when the processor 2 executes the computer program, the following Steps in the first embodiment.

[0099] To sum up, the method and terminal for evaluating the legibility of document text provided by the present invention render the original document respectively through the ordinary document renderer and the transparent text document renderer, compare the rendered pictures, and calculate The average LAB distance calculates the document readability index based on the average LAB distance, which realizes the automatic evaluation of document readability by computer, which not only improves the efficiency, accuracy and speed of document readability evaluation, but also reduces labor costs. In addition, before carrying...

Abstract

The invention discloses a method and terminal for evaluating the readability of a document text, and the method comprises the steps: carrying out the rendering of an original document through a commondocument renderer, and generating a first image; rendering all texts on the original document in a transparent manner by using a preset transparent text document renderer, and removing pixels of thetexts while maintaining fonts, word sizes and typesetting position attributes of the texts to generate a second picture; comparing the first picture with the second picture, and calculating an LAB average distance of the difference pixels; and calculating a text readability index according to the LAB average distance of the difference pixels. The original document is rendered through the common document renderer and the transparent text document renderer, the LAB average distance of the difference pixels of the rendered picture is calculated, and the document readability index is further calculated according to the calculation result, so that automatic evaluation of the document readability is achieved. Not only are the high efficiency, accuracy and evaluation speed of document readabilityevaluation improved, but also the labor cost is reduced.

Description

technical field [0001] The invention relates to the technical field of document detection, in particular to a method and a terminal for evaluating the legibility of document text. Background technique [0002] The legibility of the document text describes how the viewer recognizes each individual character in the process of text layout design, and is often related to the printing, size and appearance of the text. The legibility of the text determines the Whether the viewer can accurately identify the text content. [0003] At this stage, the legibility evaluation of document text mainly relies on human eyes for evaluation, which obviously has the following shortcomings: [0004] 1. The cost of manual evaluation is high and the efficiency is low; [0005] 2. It is easy to cause misjudgment due to eye fatigue, and the accuracy is low; [0006] 3. The evaluation speed is slow, which is not suitable for evaluating a large number of documents. Contents of the invention [0...
