Problems solved by technology
However, due to the portability of the electronic reading terminal, the size of the reading screen is bound to be limited.
In the current reading experience of various electronic reading terminals, it is very inconvenient to read scanned documents. If you display all the scanned pictures in the size of a book page on a small screen, you will feel that the words are too small; if you use partially enlarged scanned pictures Read in a different way, you need to frequently select the enlarged area, which will affect the user's reading experience

Embodiment Construction
[0027] The technical solutions of the present invention are further described below with reference to the accompanying drawings and through specific embodiments.
[0028] figure 1 This is a flow chart of rearranging the scanned version of the document in the specific embodiment of the present invention. like figure 1 As shown, the process of rearranging the scanned document includes the following steps:
[0029] Step 101 , generating an image from the scanned version of the document and converting it into a binary image. There can be various methods to convert the original image to binary image, such as global adaptive thresholding method, local thresholding method and so on. Without loss of generality, a global adaptive threshold method is used to transform the binary image.
[0030] Step 102: Perform run-length smoothing on the binary graph, obtain a connected domain for the binary graph after the run-length smoothing process, and record the position of the circumscribed...

The invention discloses a method for resetting a scanned document. The method comprises the steps of: firstly, generating an image from the scanned document, converting the image into a binary image, carrying out run-length smoothing on the binary image, determining a connected domain, horizontally merging and vertically merging to obtain a text paragraph position, determining a document paragraph area according to the obtained picture position and the text paragraph position, calculating the width-height ratio of each document paragraph area and the width-height ratio of a display screen, judging whether the width-height ratio of the document paragraph area meets a preset condition, if so, carrying out no processing, if not, splitting into a plurality of document paragraph areas meeting the preset condition; determining a reading order of all document paragraph areas, and providing reading by screens according to the order. By adopting the technical scheme disclosed by the invention, the scanned document in electronic reading is automatically subject to subfield operation, and the scanned document is displayed by screens according to the automatically divided areas, and the frequency of selecting an amplified area is reduced.
Description
technical field [0001] The invention relates to the technical field of electronic reading, in particular to a method for rearranging a scanned version of a document. Background technique [0002] Today, with the rapid development of science and technology, especially with the rapid development of Internet technology, people's reading habits are no longer limited to reading traditional paper publications. Electronic reading has become very popular and its proportion is gradually increasing. Due to the portability of e-reading terminals (e-books, mobile phones, etc.), people can read e-reading in the fragmented time of their lives, such as when taking a bus, subway, or even in a few minutes when queuing to buy a ticket. read. [0003] E-reading material comes from a variety of sources, some from electronic publications and some from scanned versions of paper publications. However, due to the portability of the electronic reading terminal, the size of the reading screen is bo...
