Since deep learning was introduced into style transfer, remarkable results have been achieved in it and it is widely used in multimedia fields, such as photography. However, the computational costs of the existing state-of-the-art (SOTA) arbitrary style transfer algorithms are still too complex to apply them on mobile device and high resolution, and their performance on shape retention is not satisfactory enough. To deal with the above problems, we propose a novel arbitrary style transfer algorithm. Specially, we propose a new network which ensures the low computational cost and high shape retention. Moreover, we propose the weighted style loss function to improve the performance on style migration. The experimental results show that the proposed algorithm achieves better results with lower computational cost than the SOTA algorithms.
