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 present disclosure relates to a method, a device, a storage medium and an electronic device for aligning document pictures, which are used to solve the problem in the prior art that manual alignment is required before document picture comparison. The method includes: respectively generating picture sequence information in the first document and the second document; and determining the first document and the second document by comparing the pictures in the first document and the second document The common picture pair in the picture sequence information of the first document and the picture sequence information of the second document, the symbol pair corresponding to the common picture pair is taken as the same symbol, and determined according to the maximum common subsequence algorithm The maximum common subsequence in the picture sequence information of the first document and the picture sequence information of the second document; pairing the pictures corresponding to each symbol in the maximum common subsequence in the first document and the The alignment is done in 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 ...
