Our solution consists of three EfficientNet-B7 models (we used the Noisy Student pre-trained weights). We did not use external data, except for pre-trained weights. One model runs on frame sequences (a 3D convolution has been added to each EfficientNet-B7 block). The other two models work frame-by ...

Overview. We partnered with other industry leaders and academic experts in September 2019 to create the Deepfake Detection Challenge (DFDC) in order to accelerate development of new ways to detect deepfake videos.

快一个月没有更新公众号了，因为这段时间的业余时间基本都拿来肝这个比赛了。业精于勤荒于嬉，该写的文章还是要写的！今天这篇文章算是对自己参加过的比赛进行一个复盘，包括整理自己在这个比赛中的收获以及介绍…

Nov 2, 2024 · DFDC Preview数据集的构建基于深度伪造检测挑战（Deepfake Detection Challenge）的预览版本。该数据集通过收集和处理大量真实与伪造的视频片段，采用先进的图像处理技术，如生成对抗网络（GANs）和深度学习模型，生成高质量的伪造视频。

The DFDC (Deepfake Detection Challenge) is a dataset for deepface detection consisting of more than 100,000 videos. The DFDC dataset consists of two versions: Preview dataset. with 5k videos. Featuring two facial modification algorithms. Full dataset, with 124k videos. Featuring eight facial modification algorithms

Jun 12, 2020 · Deepfakes are a recent off-the-shelf manipulation technique that allows anyone to swap two identities in a single video. In addition to Deepfakes, a variety of GAN-based face swapping methods have also been published with accompanying code. To counter this emerging threat, we have constructed an extremely large face swap video dataset to enable the training …

Nov 2, 2024 · Deepfake Detection Challenge (DFDC) 数据集是一个用于检测深度伪造视频的数据集。该数据集包含了大量经过处理的面部视频，其中一些视频是经过深度伪造技术生成的，而另一些则是真实的。数据集的目的是帮助研究人员开发和评估深度伪造检测算法。

DFDC 全称 Deepfake Detection Challenge，是一个用于 deepfake 检测的数据集，由 10 万多个视频组成。 DFDC 数据集由两个版本组成： 预览数据集。包含 5k 个视频，两种面部 […]

Apr 11, 2024 · 一、DFDC数据集介绍. DFDC数据集体积高达472GB，包括了119,197个视频，每个视频时长都为10秒，但是帧率从15~30fps不等，分辨率也从320x240~3840x2160不等。训练视频中有19,197个视频是由大约430名演员真实拍摄的片段，剩余100,000个视频是由真实视频生成的假脸视频。假脸生成使用了DeepFakes, Face2Face等多种主流 ...

Oct 19, 2019 · In this paper, we introduce a preview of the Deepfakes Detection Challenge (DFDC) dataset consisting of 5K videos featuring two facial modification algorithms. A data collection campaign has been carried out where participating actors have entered into an agreement to the use and manipulation of their likenesses in our creation of the dataset. …
