Embodiment Construction
[0047] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.
[0048] First, an application scenario of the embodiment of the present disclosure is described. For a document with many pictures, these pictures often have a certain logical sequence relationship. When editing a document, it may be necessary to replace the original picture or add or delete pictures, resulting in two These pictures in a document lose their original corresponding relationship. In this case, when two documents need to compare the differences, it is first necessary to align the pictures of the two documents, that is, to find which pictures are unaltered pictures, Then determine which pictures are added and which pictures are deleted according to...

The invention relates to a method and a device for aligning document pictures, a storage medium and electronic equipment, which are used for solving the problem that manual alignment is needed beforedocument picture comparison in the prior art. The method comprises the steps: generating picture sequence information in a first document and picture sequence information in a second document respectively; Determining a common picture pair in the first document and the second document by comparing pictures in the first document and the second document; Taking the symbol pair corresponding to the common image pair in the image sequence information of the first document and the image sequence information of the second document as the same symbol, and determining a maximum common sub-sequence inthe image sequence information of the first document and the image sequence information of the second document according to a maximum common sub-sequence algorithm; And aligning the picture pair corresponding to each symbol in the maximum common subsequence in the first document and the second document.
Description
technical field [0001] The present disclosure relates to the field of text comparison, and in particular, relates to a method, device, storage medium and electronic device for aligning document images. Background technique [0002] Sometimes there are many pictures in a document, and these pictures often have a certain logical sequence relationship. When editing a document, sometimes it is necessary to replace the original picture or add or delete pictures, resulting in the loss of the original correspondence between the pictures in the two documents. When two documents need to compare the differences, at present, only by manually selecting pictures for pairwise comparison, it is technically impossible to automatically select relevant pictures for comparison. [0003] For example, there are 500 pictures in a document, and there are 498 pictures in the new document after the version change. New pictures may be inserted into the new document, and some original pictures may be ...
