IMAGE RECOGNITION METHOD AND APPARATUS, IMAGE CLASSIFICATION METHOD AND APPARATUS, ELECTRONIC DEVICE, AND STORAGE MEDIUM

WIPO Patent Application WO/2020/239015

A1

Embodiments of the present application provide an image recognition method and apparatus, an image classification method and apparatus, an electronic device, and storage medium. The image recognition method comprises: acquiring an image to be classified; analyzing said image on the basis of a picture-in-picture image recognition model to determine whether said image is a picture-in-picture image; and if not, analyzing said image on the basis of a first classification model to determine the pornographic level category of said image, or if yes, analyzing said image on the basis of a second classification model to determine the pornographic level category of said image. The second classification model is different from the first classification model. The second classification model is obtained by machine learning training using a second data set and then changing the global average pooling layer and convolution kernel on the basis of the trained model, and can accurately recognize the pornographic level category of said image which is a picture-in-picture image, thereby achieving accurate recognition of the picture-in-picture image comprising vulgar pornography.
