The invention belongs to the technical field of generative adversarial networks and style migration in computer vision, and discloses an arbitrary style migration method and system, a storage medium, computer equipment and a terminal.The input of an arbitrary style migration system network is composed of a content image Ic and a style image Is, and the output of the arbitrary style migration system network is a stylized image Ics; the network structure is composed of an image encoder Enc, an adaptive channel network AdaNet, a decoder Dec, a discriminator D and an auxiliary classifier Q, the arbitrary style migration method comprises the following steps: training an arbitrary style migration network model by utilizing a training data set; and after the training of the network model is completed, network feedforward is carried out by using an image encoder Enc, an adaptive channel network AdaNet and a decoder Dec, so that a stylized image can be obtained. According to the method, the visual performance of the generated artistic image is improved, the defects of fuzzy blocks, color blocks, meaningless lines and the like existing in the image generated by the existing method are eliminated, and clearer image details are achieved.
