Problems solved by technology

[0002] In the prior art, image style recognition adopts manual feature extraction or common cnn classification model to extract image features for recognition. However, manually extracting image texture features as image style representation and building a mathematical or statistical model for style is too inefficient. Low, and it is difficult to be widely used, and the high-level extracted by the CNN classification model often includes a combination of abstract features such as color, texture, style, etc., and these features are highly abstract and will lose many details, resulting in low performance in image style recognition

Abstract

The invention provides an image style recognition method, an image style recognition device, computer equipment and a storage medium. The image style recognition method comprises the steps of: establishing a convolutional neural network, inputting a to-be-recognized image into the convolutional neural network to obtain m convolution feature maps, wherein m is greater than 1; compressing each convolution feature map into n-dimensional vectors to obtain m n-dimensional vectors, and performing inner product calculation on every two n-dimensional vectors to obtain an m*m Gram matrix; and inputtingthe m*m Gram matrix into a shallow network for classification, and outputting an image style of the to-be-recognized image. According to the image style recognition method and the image style recognition device, an intermediate feature map is extracted as a style feature, style features better than those of a full connection layer are obtained, the correlation features of the feature maps are calculated, the shallow network is used for learning the features, better style representation is obtained, the classification performance is improved, end-to-end learning is achieved in the process, andthe image style recognition method is simpler and more convenient than manual feature extraction.
