Currently, masi deepfake, face-swapping deepfake techniques are widely spread, generating a significant number of highly realistic fake videos that threaten the privacy of people and countries. Due to their devastating impacts on the world, distinguishing between real and deepfake videos has masi deepfake a fundamental issue.

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. Jay Kuo , Iacopo Masi. 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. Image Generation. Adversarial Attack Adversarial Robustness. The current spike of hyper-realistic faces artificially generated using deepfakes calls for media forensics solutions that are tailored to video streams and work reliably with a low false alarm rate at the video level.

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.

The Python scripts are available in the Supplemental Files. Recently, the deepfake techniques for swapping faces have been spreading, allowing easy creation of hyper-realistic fake videos. Detecting the authenticity of a video has become increasingly critical because of the potential negative impact on the world. The YOLO-Face detector detects face regions from each frame in the video, whereas a fine-tuned EfficientNet-B5 is used to extract the spatial features of these faces. The experimental analysis approves the superiority of the proposed method compared to the state-of-the-art methods.

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.

Several research papers have been presented in this area; facial landmark detection-based methods [ 2 , 3 ], Viola—Jones face detector [ 4 ], dlib detector [ 5 ], BlazeFace [ 6 ], RetinaFace [ 7 ], and multi-task convolution neural network MTCNN [ 8 ], to name just a few. Khalil S. It created by plotting false positive and true positive rates on X and Y axes, respectively [ 53 ]. Mehra [ 44 ] uses the Mobilenet SSD face detector to detect the face region from video frames that are selected using the frame selection method. Abstract Currently, face-swapping deepfake techniques are widely spread, generating a significant number of highly realistic fake videos that threaten the privacy of people and countries. Face Recognition Facial Inpainting. 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. These faces are aligned using a facial landmark detection algorithm. The spatial-visual features are fed to the XGBoost recognizer to distinguish between real and deepfake videos. Zaki , 3 and Kamal Eldahshan 3. Dolhansky B. It is created to be flexible and highly efficient. The global max pool two-dimensional layer is added, and it is followed by two fully connected layers with and units, respectively. De Lima O. Deepfakes: A new threat to face recognition?

The current spike of hyper-realistic faces artificially generated using deepfakes calls for media forensics solutions that are tailored to video streams and work reliably with a low false alarm rate at the video level. We present a method for deepfake detection based on a two-branch network structure that isolates digitally manipulated faces by learning to amplify artifacts while suppressing the high-level face content. Unlike current methods that extract spatial frequencies as a preprocessing step, we propose a two-branch structure: one branch propagates the original information, while the other branch suppresses the face content yet amplifies multi-band frequencies using a Laplacian of Gaussian LoG as a bottleneck layer.

Srivastava N. Due to their devastating impacts on the world, distinguishing between real and deepfake videos has become a fundamental issue. The proposed scheme introduces an effective method for detecting deepfakes in videos. Evaluation Measures The AUC is a popular evaluation metric utilized to assess the usefulness of the suggested deepfake video detection method. The YOLO face detector is employed to detect faces from video frames. Zhang Z. De Lima O. Nguyen H. Table 4 The proposed model performance. Afterwards, a couple of fully connected layers together with a rectified linear activation function ReLU are added, where each layer is followed by a dropout layer. The autoencoder extracts hidden features of face photos and the decoder reconstructs the face photos. Moreover, CNN assures its success in automatically learning the key features from images and videos. Chen W. Section 5 presents the conclusion and future work.
