Abstract

The invention relates to an image recognition method and device. The method comprises the following steps that: the features of a target image are extracted; dimensionality reduction is performed on the features of the target image according to a principal component analysis method; and the target image which has been subjected to dimensionality reduction is recognized according to a pre-trained image model. With the image recognition method adopted, a terminal can perform dimensionality reduction on the features of the target image according to the principal component analysis method, and therefore, the number of the features of the target image can be decreased, and the key features of the target image can be reserved; the terminal can recognize the target image which has been subjected to dimensionality reduction according to the pre-trained image model; and therefore, the efficiency of image recognition can be improved, and the accuracy of image recognition will not be reduced, and the use experience of a user can be improved.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, and in particular to an image recognition method and device. Background technique [0002] In related technologies, when performing image recognition, it is usually necessary to first extract features of a target image to be recognized, and then recognize the target image based on a preset model. In this process, many features are often extracted, such as: 2000-dimensional features, which will affect the speed of target image recognition, especially when there are a large number of target images to be recognized, greatly affecting the user experience. Contents of the invention [0003] In order to overcome the problems existing in related technologies, the present disclosure provides an image recognition method and device. [0004] According to a first aspect of an embodiment of the present disclosure, an image recognition method is provided, including: [0005] Extract the ...
