摘要:

人脸素描合成与识别在数字娱乐和执法领域有着广泛的应用。最近,基于生成对抗网络(GANs)的方法显着提高了图像合成的质量,但它们没有明确考虑识别的目的。在本文中,我们首先提出了一种身份感知CycleGAN(IACycleGAN)模型,该模型应用了一种新的感知损失来监督图像生成网络。它改进了CycleGAN的照片素描合成,更加关注关键面部区域的合成,如眼睛和鼻子,这对身份识别很重要。此外,我们开发了合成模型和识别模型之间的相互优化过程,该过程通过IACycleGAN迭代合成更好的图像,并通过生成的和真实样本的三重丢失来增强识别模型。使用广泛使用的CUFS和CUFSF数据库上的photo-to-sketch和sketch-to-photo任务进行了广泛的实验。实验结果表明,该方法在合成图像质量和草图识别精度方面均优于现有的几种方法。

英文摘要:

Face photo-sketch synthesis and recognition has many applications in digital entertainment and law enforcement. Recently, generative adversarial networks (GANs) based methods have significantly improved the quality of image synthesis, but they have not explicitly considered the purpose of recognition. In this paper, we first propose an Identity-Aware CycleGAN (IACycleGAN) model that applies a new perceptual loss to supervise the image generation network. It improves CycleGAN on photo-sketch synthesis by paying more attention to the synthesis of key facial regions, such as eyes and nose, which are important for identity recognition. Furthermore, we develop a mutual optimization procedure between the synthesis model and the recognition model, which iteratively synthesizes better images by IACycleGAN and enhances the recognition model by the triplet loss of the generated and real samples. Extensive experiments are performed on both photo-tosketch and sketch-to-photo tasks using the widely used CUFS and CUFSF databases. The results show that the proposed method performs better than several state-of-the-art methods in terms of both synthetic image quality and photo-sketch recognition accuracy.
