Abstract

The embodiment of the invention provides an image retrieval method and device and a computer readable storage medium. According to the image retrieval method provided by the embodiment of the invention, the aspect ratio of the image is taken as a global feature point, a vocabulary tree and a vocabulary forest are constructed by utilizing mixed feature points including the global feature point anda local feature point, and a first layer of the vocabulary tree is constructed by utilizing the global feature point. According to the embodiment of the invention, the calculation amount and the retrieval time of image retrieval can be reduced, and the image retrieval effect is improved.

Description

technical field [0001] The invention relates to the technical field of dialogue processing, in particular to an image retrieval method, device and computer-readable storage medium. Background technique [0002] With the development of Internet and multimedia technology, multimedia information, especially image information, is being generated and disseminated at an explosive speed. Image retrieval technology can enable users to quickly and accurately find and access the desired images in various image information, and has broad application prospects in the field of network multimedia. [0003] For example, uploading an image on some retrieval websites (such as Google, Baidu, etc.), can retrieve similar images of the image. For another example, on some shopping websites, people can use mobile phones to take pictures and upload them, so that they can search for corresponding products. For another example, for a drug management system, precise matching based on query images ca...
