Abstract

The invention is suitable for the technical field of image processing, and provides an image classification method, an image classification device and terminal equipment, and the method comprises thesteps: obtaining a to-be-detected image; obtaining global features of the to-be-detected image, wherein the global features refer to feature vectors extracted from the whole to-be-detected image; acquiring local features of the to-be-detected image through a random frame, wherein the local features refer to feature vectors extracted from a local area of the whole to-be-detected image; and inputting the global features and the local features into a classifier, wherein the classifier outputs the category of the to-be-detected image. According to the invention, the accuracy of image classification can be improved.

Description

technical field [0001] The present application belongs to the technical field of image processing, and in particular, relates to an image classification method, an image classification device and a terminal device. Background technique [0002] In recent years, image classification has aroused great research interest, and has been successfully deployed in many application products, such as mobile phones, personal computers and other terminal devices, intelligently solving many practical image processing problems. [0003] With the rapid development of deep learning technology, deep learning has become an advanced technology in image classification. However, the existing image classification methods usually use deep learning to extract the global features of the entire image for image classification. For some images with similar categories, they cannot be accurately classified. SUMMARY OF THE INVENTION [0004] The present application provides an image classification metho...
