Embodiment Construction

[0060] In order to make the purpose and technical solution of the present invention clearer, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0061] Such as figure 1 As shown, the specific implementation of the embodiment of the present invention includes the following steps:

[0062] Step 1. Construct an image semantic extraction model based on deep hashing. The model is divided into nine processing layers: including five convolutional layers, two fully connected layers, a hashing layer, and an output layer; each processing layer The specific strategies are shown in Table 1:

[0063]

[0064] Among them, the convolution processing layer C i Contains three processing steps of convolution, activation and pooling, expressed as:

[0065]

[0066] in, Is the convolutio...

Abstract

The invention discloses a digital humanities-oriented mobile visual retrieval method. The method comprises: firstly, constructing a deep hashing-based image semantic extraction model; initializing parameters of all processing layers of the model through pre-training; constructing a loss function suitable for use in the field of digital humanities; collecting digital-humanities image samples, and constructing a model training data set and a verification set; pre-processing the image samples; using the constructed loss function and the digital-humanities training set to train the model to optimize the model parameters; and using the model, of which training is completed, to extract image semantic feature vectors, and completing an image retrieval process. For two major challenges of image deep-semantic-feature extraction and data transmission size limitation in mobile visual retrieval of the digital humanities, the invention provides the deep hashing-based mobile visual search (MVS) method of the digital humanities by combining deep learning and a hashing method, and the mobile visual search method has outstanding performance on the data sets of the field of the digital humanities.

Description

technical field [0001] The invention relates to the fields of digital humanities, mobile visual retrieval, etc., and in particular to a digital humanities-oriented mobile visual retrieval method. Background technique [0002] With the popularization of mobile smart terminal equipment and the rapid development of big data and cloud computing technology, massive pictures, videos, 3D models and other visual content have been generated on the Internet; the portability of mobile devices and the ubiquity of wireless networks make information retrieval more difficult. The method tends to be mobile and multimedia. Mobile Visual Search (MVS) technology, that is, an information retrieval model that uses visual data such as images, videos or maps collected by mobile smart terminals as retrieval objects to obtain relevant information, is gradually developing. rise, and have generated huge market and application demands. The application of MVS to the field of digital humanities has emer...
