In the exemplar-based image inpainting approach,there are usually two major problems:the unreasonable calculation of priority and only considering the color features in the patch lookup *** this paper,we propose an image inpainting approach based on the structural tensor edge intensity ***,we use the progressive scanning inpainting method to avoid the image filling order being affected by the priority ***,we use the edge intensity model to build the patches similarity function for correctly identifying the local image ***,the balance operator is used to restrict the excessive propagation of structural information to ensure the correct structural *** experimental results show that the our approach is comparable and even superior to some state-of-the-art inpainting algorithms.

Graphene nanoplatelets （GNPs） were used as multifunctional nanofiller to enhance thermal and mechanical properties as well as electrical conductivity of two different biodegradable thermoplastics： poly lactide （PLA） and poly （butylene adipate-co-terephthalate）（PBAT）. Morphological investigations showed different levels of GNP dispersion in the two matrices, and consequently physical properties of the two systems exhibited dissimilar behaviours with GNP incorporation. Crystallinity of PLA, determined from differential scanning calorimetry, was observed to increase markedly with addition of GNPs in contrast to the decrease in crystallinity of PBAT. Isothermal and non-isothermal thermogravimetric analyses also revealed a more significant delay in thermal decomposition of PLA upon addition of GNPs compared to that of PBAT. Furthermore, results showed that increasing GNP content of PLA and PBAT nanocomposites influenced their Young＇s modulus and electrical conductivity in different ways. Modulus of PBAT increased continuously with increasing GNP loading while that of PLA reached a maximum at 9wt% GNPs and then decreased. Moreover, despite the higher conductivity of pure PBAT compared to pure PLA, conductivity of PLA/GNP nanocomposites overtook that of PBATIGNP nanocomposites above a certain GNP concentration. This demonstrated the determining effect of nanoplatelets dispersion state on the matrices properties.

为提升基于深度学习语音增强方法的性能,提出融合膨胀卷积与自注意力的CycleGAN语音增强模型。为提升生成器特征映射能力,在编解码器部分,使用普通卷积与膨胀卷积进行双路连接,以扩大网络感受野,更好获取上下文信息;转换层部分采用密集连接的方式堆积一维膨胀残差模块,改善网络的信息流并提供更多梯度传播方式;在跳跃连接部分加入了自注意力和特征增强模块,抑制冗余信息,弥补编解码过程中的信息丢失。实验表明,优化后,该模型语音质量感知指标提高0.09,语音可懂度指标提高0.02,降噪效果更好。
