Abstract

The invention discloses an image recognition method, device and computer storage device for electronic documents. First, a document page image is divided into blocks to obtain a plurality of page image blocks; then feature extraction is performed on the plurality of page image blocks respectively, Obtain a plurality of corresponding feature vectors; further perform labeling data sampling according to the plurality of feature vectors; then perform model training according to the plurality of feature vectors and the sampled labeling data to obtain a prediction model; finally, use the prediction model to Image recognition is performed on the plurality of page image blocks to obtain a target predicted image.

Description

technical field [0001] The present invention relates to electronic document application technology, in particular to an image recognition method, device and computer storage device for electronic documents. Background technique [0002] With the rapid development of computer and network technology, the application of electronic documents is more and more extensive, especially the layout documents in PDF and other formats. At present, the methods of image recognition for document pages mainly include the global recursive cutting algorithm based on XY tree and the object detection algorithm based on deep learning. [0003] However, the above methods of image recognition for document pages currently have the following defects: 1) The global recursive cutting algorithm based on XY tree cannot effectively cut specific layouts (such as tables, dividing lines); 2) It is mainly based on the blank of the projection The segmentation is performed at intervals, and the interval as the ...
