Abstract

The invention provides an image classification method and apparatus, an electronic device and a storage medium. The method comprises the steps of determining a feature representation of each pixel in a to-be-classified image; based on the feature representation of each pixel and the global feature representation corresponding to each preset category, determining a feature enhancement representation of each pixel; based on the feature representation and the feature enhancement representation of each pixel, determining a preset category corresponding to the to-be-classified image, wherein the global feature representation is determined based on the sample image and a preset category corresponding to each pixel in the sample image. According to the method, the device, the electronic equipment and the storage medium provided by the invention, the expression capability of details in the image is improved by adopting a pixel-level feature enhancement mode, and the classification accuracy of the image is improved.

Description

technical field [0001] The present invention relates to the technical field of computer vision, in particular to an image classification method, device, electronic equipment and storage medium. Background technique [0002] Deep learning is a popular research direction in the field of machine learning in recent years, and has achieved great success in computer vision, natural language processing and other fields. In particular, deep convolutional neural networks show superior performance in image classification tasks by virtue of local receptive fields, shared weights, and feature downsampling. [0003] In the prior art, images are generally classified by extracting image features. Image features are often extracted based on the entire image, and the ability to express details in the image is poor, resulting in poor image classification accuracy. Contents of the invention [0004] The invention provides an image classification method, device, electronic equipment and stor...
