In this situation, the task of image forensics is urgent. The existing methods examine generated images and claim a forgery by detecting visual artifacts or invisible patterns, resulting in generalization issues. We observed that the noise pattern of real images exhibits similar characteristics in the...
We further show that these two cues can be used to distinguish GAN-generated imagery from camera imagery, demonstrating effective discrimination between GAN imagery and real camera images used to train the GAN. 展开 关键词: Computer Science - Computer Vision and Pattern Recognition ...
In this work, we describe a new deep learning based method that can effectively distinguish AI-generated fake videos (referred to as {\em DeepFake} videos hereafter) from real videos. Our method is based on the observations that current DeepFake algorithm can only generate images of limited reso...
来自Adobe 和加州伯克利的研究人员在论文预印本平台 arXiv 上传了《CNN-generated images are surprisingly easy to spot... for now》,他们提出,即使是在一种 CNN 生成的图像所训练的分类器,也能够跨数据集、网络架构和训练任务,展现出惊人的泛化能力。这篇论文目前已被 CVPR 2020 接收,代码和模型也已公布。 ...
Full size image Global coherence in real spatial systems The situation with EEG data is illustrated in left panels of Fig. 4. The first crucial observation is that, as expected in epilepsy dynamics, spatial coherent patterns are not time invariant, but instead they exhibit a rich time-frequency...
Therefore, we develop a synthetic data gen- eration pipeline where a fake image is generated by blend- ing pseudo source and target images from a single image to give models a more general and difficult task for face forgery detection. To achieve this, we introduce self-blended images (SB...
Full size image Real-world dataset: genome-wide chromosome conformation capture (Hi-C) Besides the artificially generated networks, we tested this algorithm on a real-world dataset from biology. For this, we analyzed time series corresponding to a genome-wide chromosome conformation capture (Hi-C)...
The Oxford Nanopore (ONT) platform provides portable and rapid genome sequencing, and its ability to natively profile DNA methylation without complex sample processing is attractive for point-of-care real-time sequencing. We recently demonstrated ONT sha
Taking this real-world scenario of printed and scanned face images into account, [6] focuses on the effect of the print-scan process of a digitally mor- phed face image on FRSs and morphing detection. The print and scan process adds some noise and granularity to the face image, which ...
an array of photosensitive elements, for detecting time-dependent image data, including an array of cells each having a photosensor generating a signal dependent on a light intensity at the cell. Real time artificial vision using a photoarray, such as is disclosed in U.S. Patent Application ...
