Abstract

The invention discloses an image retrieval method and apparatus, an image information acquisition method and apparatus, an image identification method and apparatus, an image identification system, a method and apparatus used for calculating an image feature value, and an electronic device. The image retrieval method comprises the steps of extracting a local feature of a to-be-retrieved image; calculating a feature value of the local feature by adopting a pre-trained depth autoencoder network model; performing matching on the feature value and feature values of registered images in an image retrieval database; and selecting a registered image, which meets a preset condition, as a retrieval result of the to-be-retrieved image according to a matching result. By adopting the method, a depth autoencoder network can effectively keep distance information and a distinguishing capability between the feature values in a process of performing compressed representation on the local feature, so that the image retrieval precision can be effectively improved, the workload of rearrangement and filtration can be reduced, and the retrieval efficiency can be enhanced.

Description

technical field [0001] The present application relates to image retrieval technology, in particular to an image retrieval method and device. The present application also provides a method and device for acquiring image information, an image recognition method and device, an image recognition system, a method and device for calculating image feature values, and an electronic device. Background technique [0002] Object recognition and visual search technology can greatly shorten the distance between the physical world and the data world, and help users obtain information quickly and conveniently. In the field of the Internet that has attracted much attention at present, for the images to be identified that are captured by cameras or downloaded from the Internet, image retrieval technology can be used to find matching images from pre-registered images, and further learn about the images to be identified. The relevant information of the book (this process is usually also calle...
