针对复杂背景下服装图像局部区域风格迁移难以控制及迁移后容易产生边界伪影的问题,提出一种基于注意力机制的CycleGAN服装局部风格迁移方法。通过VGG16网络分别提取服装图像的内容特征与风格特征,将其输入基于注意力机制的CycleGAN生成器中,应用注意力机制在复杂背景下的各个服装区域分配概率分布信息,获得注意力分布更多的区域及相关度更高的区域,并采用改进的损失函数校正边界伪影,对该区域进行风格迁移得到所需的风格迁移服装图像。实验结果表明,与CNN、FCN、BeautyGAN图像局部风格迁移方法相比,该方法不仅可以突出服装图像局部风格迁移效果,而且增强了图像细节,有利于提高输出图像的真实性和艺术性。 相似文献

According to the configuration, mixed-conducting membranes are classified as symmetric membranes and asymmetric membranes consisting of a thin dense layer and a porous support. In this study, these two kinds of SrCo0.4Fe0.5Zr0.1O3-δ oxide-based membranes were systematically compared in terms of oxygen permeability and chemical stability, and their differences were elucidated by means of the theoretical calculation. For the oxygen permeability, the asymmetric membrane was greater than the symmetric membrane due to the significant decrease of bulk diffusion resistance in the thin dense layer of the asymmetric membrane. In regard to the chemical stability, the increase of oxygen partial pressure on the asymmetric membrane surface at CH4side produced the stable time of over 1032 h in partial oxidation of methane at 1123 K, while the symmetric membrane was only of 528 h. This study demonstrated that the asymmetric membrane was a promising geometrical configuration for the practical application. 相似文献
