摘要:

人脸素描合成在多媒体娱乐和执法领域有着广泛的应用。尽管最近在深度神经网络方面取得了进展,但由于人脸的多样性和复杂性,准确和逼真的人脸草图合成仍然是一项具有挑战性的任务。当前基于图像间距离的人脸草图合成方法在小规模数据集上经常遇到过拟合问题。为了解决这个问题,我们提出了一个端到端的面向记忆的风格传输网络(MOST-Net)的人脸草图合成,可以产生高保真的草图与有限的数据。具体来说,外部自我监督的动态记忆模块被引入到捕获的领域对齐知识的长期。通过这种方式,我们提出的模型可以获得域转移能力,通过建立持久的关系之间的面孔和相应的草图在特征层。此外,我们设计了一种新的内存细化损失(MR损失)的内存模块中的特征对齐,这提高了内存插槽的准确性,在一个无人监督的方式。在CUFS和CUFSF数据集上的大量实验表明,我们的MOST-Net达到了最先进的性能,特别是在结构相似性指数(SSIM)方面。

英文摘要:

Face sketch synthesis has been widely used in multi-media entertainment and law enforcement. Despite the recent developments in deep neural networks, accurate and realistic face sketch synthesis is still a challenging task due to the diversity and complexity of human faces. Current image-to-image translation-based face sketch synthesis frequently encounters over-fitting problems when it comes to small-scale datasets. To tackle this problem, we present an end-to-end Memory Oriented Style Transfer Network (MOST-Net) for face sketch synthesis which can produce high-fidelity sketches with limited data. Specifically, an external self-supervised dynamic memory module is introduced to capture the domain alignment knowledge in the long term. In this way, our proposed model could obtain the domain-transfer ability by establishing the durable relationship between faces and corresponding sketches on the feature level. Furthermore, we design a novel Memory Refinement Loss (MR Loss) for feature alignment in the memory module, which enhances the accuracy of memory slots in an unsupervised manner. Extensive experiments on the CUFS and the CUFSF datasets show that our MOST-Net achieves state-of-the-art performance, especially in terms of the Structural Similarity Index(SSIM).
