摘要

人脸识别受到许多因素的影响,如低分辨率图像、数据集的可用性、光照、姿态不变性、老化、表情等。随着功能强大的gpu的可用性越来越高,我们正在使用大量数据集来提高准确性。在可用于任何面部识别算法训练的不同数据集中,很少有数据集可以在低配置系统上运行。然而,同样的方法不能产生令人满意的FaceSwap结果,因为其中存在异常。创建了一个包含20个恒等式的小数据集,在此基础上观察了本文的结果。本文介绍了使用DeepFakes算法来提高FaceNet的性能,该算法采用了SqueezeNet架构和softmax损失函数。数据越多,性能越好。然后使用DeepFakes的FaceSwap变体来交换身份并为给定身份创建假图像。然后,使用FaceNet在新形成的数据集250RF上使用假图像和原始数据集200R进行人脸识别。通过对比,该方法在训练精度和测试精度上都取得了令人满意的结果,从而开创了该方法的发展前景。

Improving Facial Recognition of FaceNet in a small dataset using DeepFakes
Facial recognition is affected by many factors such as low-resolution images, availability of datasets, illumination, pose invariance, ageing, expression, etc. With the increasing availability of powerful GPUs, we are using massive datasets to facilitate better accuracy. Among different datasets available to perform training of any facial recognition algorithm, very few of them can be a run on a low configuration system. Still, the same can’t be used to create satisfactory FaceSwap results because of anomalies in them. A small dataset of 20 identities has been created on which the results of this paper are observed. This paper introduces the usage of DeepFakes algorithm to improve the performance of FaceNet with SqueezeNet architecture and softmax loss function. It is expected that more data leads to better performance. Then the FaceSwap variation of DeepFakes is used to swap identities and create fake images for a given identity. Then, FaceNet is used to identify faces on the newly formed dataset 250RF using fake images and the original dataset 200R. This method achieves satisfactory results on training and testing accuracy in comparison, thereby creating prospects on such a method.
