Embodiment 1
[0059] This example provides figure 1 A data retrieval method based on a class-specific prototype deep hash network is shown, including:
[0060] S1, establish a deep hash network model; the deep hash network model learns discrete class-specific prototypes from the semantic labels of image data as the intermediate semantic representation of semantic labels, and establishes a rough semantic relationship between the hash code of image data and the class-specific prototypes , and construct the refined semantic relationship between all hash codes through paired supervisory information;
[0061] S2, acquiring target image information to be retrieved;
[0062] S3, the target image information is retrieved according to the deep hash network model, and a retrieval result is obtained.
[0063] Specifically, the retrieval process includes: preprocessing the image to be retrieved, extracting the feature vector, inputting the feature vector into the deep hash network to obtain the hash ...
Embodiment 2
[0125] like figure 2 As shown, the present embodiment provides an image data retrieval device based on a specific class prototype deep hash network, including:
[0126] memory 91 for storing computer programs;
[0127] The processor 92 is configured to execute a computer program to implement any one of the above-mentioned deep hash network image retrieval methods based on specific class prototypes.
[0128] Specifically, the processor 92 and the memory 91 are electrically connected. The processor 91 can access the memory 92, read the program and data in the memory 92, and be used to execute the image data method based on the depth hash network of the specific class prototype; The program and data of the image data method of the hash network are used to save the result obtained after the processor 92 executes the method.
Embodiment 3
[0130] This embodiment provides a non-volatile computer-readable storage medium on which computer program instructions are stored. When the computer program instructions are executed by a processor, any one of the above-mentioned deep hash network image retrieval based on a specific class prototype can be realized. method.
