A Diffusion Model Based Quality Enhancement Method for HEVC Compressed Video
Most of the existing methods need to train corresponding models for compressed videos with different quantization parameters to improve the quality of compressed videos.
Contrastive Multi-FaceForensics: An End-to-end Bi-grained Contrastive Learning Approach for Multi-face Forgery Detection
DeepFakes have raised serious societal concerns, leading to a great surge in detection-based forensics methods in recent years.
FakeTracer: Catching Face-swap DeepFakes via Implanting Traces in Training
In light of these two traces, our method can effectively expose DeepFakes by identifying them.
Automatic Block-wise Pruning with Auxiliary Gating Structures for Deep Convolutional Neural Networks
Network pruning is an effective method of model compression to handle such problems.
CenterNet++ for Object Detection
Our approach, named CenterNet, detects each object as a triplet keypoints (top-left and bottom-right corners and the center keypoint).

DeepFake-o-meter: An Open Platform for DeepFake Detection
In recent years, the advent of deep learning-based techniques and the significant reduction in the cost of computation resulted in the feasibility of creating realistic videos of human faces, commonly known as DeepFakes.
Landmark Breaker: Obstructing DeepFake By Disturbing Landmark Extraction
In this paper, we describe Landmark Breaker, the first dedicated method to disrupt facial landmark extraction, and apply it to the obstruction of the generation of DeepFake videos. Our motivation is that disrupting the facial landmark extraction can affect the alignment of input face so as to degrade the DeepFake quality.
LandmarkGAN: Synthesizing Faces from Landmarks
Face synthesis is an important problem in computer vision with many applications.
Corner Proposal Network for Anchor-free, Two-stage Object Detection

Celeb-DF: A Large-scale Challenging Dataset for DeepFake Forensics
AI-synthesized face-swapping videos, commonly known as DeepFakes, is an emerging problem threatening the trustworthiness of online information.
CenterNet: Keypoint Triplets for Object Detection
In object detection, keypoint-based approaches often suffer a large number of incorrect object bounding boxes, arguably due to the lack of an additional look into the cropped regions.

Contrast Enhancement Estimation for Digital Image Forensics
Our method recovers the original pixel histogram and the contrast enhancement simultaneously from a single image with an iterative algorithm.
Geometric Hypergraph Learning for Visual Tracking
Graph based representation is widely used in visual tracking field by finding correct correspondences between target parts in consecutive frames.
UA-DETRAC: A New Benchmark and Protocol for Multi-Object Detection and Tracking
In this work, we perform a comprehensive quantitative study on the effects of object detection accuracy to the overall MOT performance, using the new large-scale University at Albany DETection and tRACking (UA-DETRAC) benchmark dataset.
Improving Image Restoration with Soft-Rounding
In this work, we describe an effective and efficient approach to incorporate the knowledge of distinct pixel values of the pristine images into the general regularized least squares restoration framework.
