Though a common assumption is that adversarial points leave the manifold of the input data, our study finds out that, surprisingly, untargeted adversarial points in the input space are very likely under the generative model hidden inside the discriminative classifier -- have low energy in the EBM. As a result, the algorithm is encouraged to learn both comprehensive features and inherent hierarchical nature of different forgery attributes, thereby improving the IFDL representation.

We offer a method for one-shot mask-guided image synthesis that allows controlling manipulations of a single image by inverting a quasi-robust classifier equipped with strong regularizers.

Title: Towards a fully automatic solution for face occlusion detection and completion. Abstract: Computer vision is arguably the most rapidly evolving topic in computer science, undergoing drastic and exciting changes. A primary goal is teaching machines how to understand and model humans from visual information. The main thread of my research is giving machines the capability to 1 build an internal representation of humans, as seen from a camera in uncooperative environments, that is highly discriminative for identity e. In this talk, I show how to enforce smoothness in a deep neural network for better, structured face occlusion detection and how this occlusion detection can ease the learning of the face completion task. Finally, I quickly introduce my recent work on Deepfake Detection. Bio: Dr. Masi earned his Ph. Immediately after, he moved to California and joined USC, where he was a postdoctoral scholar.

Advancements in deep learning techniques and the availability of free, large databases have made it possible, even for non-technical people, to either manipulate or generate realistic facial samples for both benign and malicious purposes. DeepFakes refer to face multimedia content, which has been digitally altered or synthetically created using deep neural networks. The paper first outlines the readily available face editing apps and the vulnerability or performance degradation of face recognition systems under various face manipulations. Next, this survey presents an overview of the techniques and works that have been carried out in recent years for deepfake and face manipulations. Especially, four kinds of deepfake or face manipulations are reviewed, i.

Manipulating faces in photos or videos is a critical issue that poses a threat to world security. The third one uses the fully connected dense layer with Softmax activation function on the top of CNN directly to differentiate between real and fake videos. The InceptionResNetV2 is an Inception-style network that uses residual connections rather than filter concatenation. Instead, we compare our FPN with existing methods by evaluating how they affect face recognition accuracy on the IJB-A and IJB-B benchmarks: using the same recognition pipeline, but varying the face alignment method. Home In the news Additionally, Figure 4 shows the AUC curve corresponding to the performance of the suggested model. It is created to be flexible and highly efficient. Introduction The growing popularity of social networks such as Facebook, Twitter, and YouTube, along with the availability of high-advanced camera cell phones, has made the generation, sharing, and editing of videos and images more accessible than before. Moreover, the Nesterov-accelerated adaptive moment estimation Nadam optimizer [ 57 ] is employed together with a learning rate of 0. The work in Nguyen et al. Face Recognition. Therefore, a fine-tuned InceptionResNetV2 CNN is proposed here as a feature extractor method aiming to discover the inconsistencies in spatial information of manipulated facial video frames.

On social media and the Internet, visual disinformation has expanded dramatically.
