Embodiment Construction
[0053] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0054] Such as figure 1 As shown, in the training phase, first collect text documents to establish a document library, convert the document library documents into pictures according to paragraphs, and establish a text picture library; , GoogLeNet three network models for fine-tuning, dimension reduction and save the feature matrix of the text image library obtained from the model, and then calculate the average retrieval accuracy of the three network models, based on the obtained average retrieval accuracy of the three network models fusion The feature matrix corresponding to each model. In the retrieval stage, firstly, the retrieved document is divided into paragraphs and converted into a retrieved image set, and a series of preprocessing is performed; then, the three fine-tuned network models are used to extract features from the preprocessed retriev...
