Abstract

Embodiments of the invention provide an image classification method and device, and an electronic device. The method comprises the steps of obtaining a to-be-classified image; extracting a target feature vector of the to-be-classified image; determining a target image category corresponding to the target feature vector according to the target feature vector and a pre-established corresponding relation between the feature vector and the image category; and determining the target image category as the category of the to-be-classified image. Visibly, in the scheme, the category of the to-be-classified image can be determined only according to the target feature vector of the to-be-classified image and the pre-established corresponding relation between the feature vector and the image category, a large number of image samples do not need to be collected for training, the calculation amount is greatly reduced, the calculation time is shortened, and the image classification efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image classification method, device and electronic equipment. Background technique [0002] Computer vision refers to the extraction and analysis of image features, so that the computer has the ability of human eyes and human brain to recognize images. Image classification is one of the core problems of computer vision. Image classification is to classify images according to preset categories. The general method can be to assign a label to the input image from a fixed set of classification labels, and the label identifies the input image. category. [0003] Image classification has various applications in real life. For example, artificial intelligence devices, including robots and robotic arms, need to monitor the status of themselves and the interactive environment during the execution of tasks. One of the more commonly used methods is to acquire environme...
