Abstract

This application is applicable to the technical field of image processing, and provides a method for extracting image features, a terminal device, and a computer-readable storage medium. The method includes: obtaining the initial features of the image to be extracted, and constructing the Gradient boosting tree model of the training, obtain the gradient boosting tree model after training, and extract the feature vector of the middle layer leaf node of the gradient boosting tree model after training, the category of the label of the training sample is the target category, the described The initial feature of the image to be extracted is fused with the feature vector to obtain the target feature used to represent the target category of the image to be extracted. Through this application, the target feature that can effectively characterize the image can be extracted.

Description

technical field [0001] The present application belongs to the technical field of image processing, and in particular relates to an image feature extraction method, a terminal device, and a computer-readable storage medium. Background technique [0002] Image recognition is a recognition technology based on feature information of the same type of objects (such as face, style, etc.), such as face recognition, style recognition, etc. With the maturity of computer technology, image recognition is applied in more and more fields. [0003] At present, no matter what kind of scene is used, a common feature extraction method is used when extracting image features. However, when performing similarity calculations on the styles of two images, the extracted common features cannot effectively characterize the styles of the two images; similarly, when performing similarity calculations on the contents of two images, the extracted common features Features are also unable to effectively ...
