Abstract

The embodiment of the invention discloses an article pool generation method and device, a picture search method and device, electronic equipment and a medium. The article pool generation method comprises the steps of obtaining sample picture features of sample pictures in article pictures, dividing a feature space where the sample picture features are located, and determining visual category features of a feature subspace according to the sample picture features in the feature subspace obtained through division; for the article picture features of each article picture, dividing the article picture features into corresponding feature subspaces according to the visual category features; and for each feature subspace, generating an article pool corresponding to the visual category features ofthe feature subspace according to the article picture features in the feature subspace. According to the technical scheme of the embodiment of the invention, the article pool which belongs to the same article pool and has high consistency of the article picture features in the visual information can be generated, so that the accuracy of subsequent picture search is effectively ensured.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of computer applications, and in particular to a method for generating an item pool, a method for searching images, a device, electronic equipment, and a medium. Background technique [0002] Image search technology is currently widely used in the field of e-commerce. It searches the images to be searched uploaded by users in the item pool, which stores the item pictures and item information of each item, and then can compare the items in the item pool with The item information corresponding to the item picture that is relatively similar to the image to be searched for is returned to the user, thereby increasing the probability that the user can subsequently obtain the item corresponding to the item information. [0003] However, the following technical problems exist in the prior art: the existing item pool generation scheme may lead to the fact that it is impossible to search for ...
