| 摘 要： | 针对StarGANv2模型生成的人脸图像存在风格重建效果不佳、人脸纹理不够自然等现象，该文提出结合多尺度特征和多维注意力的人脸风格转换模型.1)将多尺度特征融合模块PSConv嵌入StarGANv2生成器内，提高了模型对图像特征的提取能力；2)提出了多维注意力模块MDConv,并将该模块嵌入StarGANv2判别器内，从而提高了模型对真假人脸图像的判别能力.与StarGANv2方法在CelebA-HQ数据集上进行对比实验的结果表明：该方法生成的人脸图像风格更美观，纹理细节更自然，学习感知图像相似度(LPIPS)的值也得到了提升.

| Abstract: | Aiming at the problem of smart contract property verification,the formal verification method of smart contract properties based on UPPAAL is proposed in this paper.The operational semantics of Solidity basic statements and its transformation to time automata are defined,and smart contracts are transformed into time automata network models.The properties of smart contracts include safety and activity.The common security and activity of smart contracts are defined and described.The model checking tool UPPAAL is used to verify the properties of smart contracts.The shopping contract is modeled and verified,which proves the effectiveness of the proposed method. |
