Avatar Fingerprinting for Authorized Use of Synthetic Talking-Head Videos

no code implementations5 May 2023 Ekta Prashnani, Koki Nagano, Shalini De Mello, David Luebke, Orazio Gallo

This allows us to link the synthetic video to the identity driving the expressions in the video, regardless of the facial appearance shown.

Generalizable Deepfake Detection with Phase-Based Motion Analysis

no code implementations17 Nov 2022 Ekta Prashnani, Michael Goebel, B. S. Manjunath

Overall, with PhaseForensics, we show improved distortion and adversarial robustness, and state-of-the-art cross-dataset generalization, with 91. 2% video-level AUC on the challenging CelebDFv2 (a recent state-of-the-art compares at 86. 9%).

LOCL: Learning Object-Attribute Composition using Localization

1 code implementation7 Oct 2022 Satish Kumar, ASM Iftekhar, Ekta Prashnani, B. S. Manjunath

This paper describes LOCL (Learning Object Attribute Composition using Localization) that generalizes composition zero shot learning to objects in cluttered and more realistic settings.

Noise-Aware Video Saliency Prediction

1 code implementation16 Apr 2021 Ekta Prashnani, Orazio Gallo, Joohwan Kim, Josef Spjut, Pradeep Sen, Iuri Frosio

We note that the accuracy of the maps reconstructed from the gaze data of a fixed number of observers varies with the frame, as it depends on the content of the scene.

PieAPP: Perceptual Image-Error Assessment through Pairwise Preference

1 code implementation CVPR 2018 Ekta Prashnani, Hong Cai, Yasamin Mostofi, Pradeep Sen

Our key observation is that our trained network can then be used separately with only one distorted image and a reference to predict its perceptual error, without ever being trained on explicit human perceptual-error labels.
