WAIT: Feature Warping for Animation to Illustration video Translation using GANs

1 code implementation7 Oct 2023 Samet Hicsonmez, Nermin Samet, Fidan Samet, Oguz Bakir, Emre Akbas, Pinar Duygulu

Current state-of-the-art video-to-video translation models rely on having a video sequence or a single style image to stylize an input video.

HybridAugment++: Unified Frequency Spectra Perturbations for Model Robustness

1 code implementation ICCV 2023 Mehmet Kerim Yucel, Ramazan Gokberk Cinbis, Pinar Duygulu

First, inspired by these observations, we propose a simple yet effective data augmentation method HybridAugment that reduces the reliance of CNNs on high-frequency components, and thus improves their robustness while keeping their clean accuracy high.

Red Carpet to Fight Club: Partially-supervised Domain Transfer for Face Recognition in Violent Videos

no code implementations16 Sep 2020 Yunus Can Bilge, Mehmet Kerim Yucel, Ramazan Gokberk Cinbis, Nazli Ikizler-Cinbis, Pinar Duygulu

To mimic such scenarios, we formulate a realistic domain-transfer problem, where the goal is to transfer the recognition model trained on clean posed images to the target domain of violent videos, where training videos are available only for a subset of subjects.

A Deep Dive into Adversarial Robustness in Zero-Shot Learning

2 code implementations17 Aug 2020 Mehmet Kerim Yucel, Ramazan Gokberk Cinbis, Pinar Duygulu

In constrast, Zero-shot Learning (ZSL) and Generalized Zero-shot Learning (GZSL) tasks inherently lack supervision across all classes.

GANILLA: Generative Adversarial Networks for Image to Illustration Translation

4 code implementations13 Feb 2020 Samet Hicsonmez, Nermin Samet, Emre Akbas, Pinar Duygulu

To address this problem, we propose a new framework for the quantitative evaluation of image-to-illustration models, where both content and style are taken into account using separate classifiers.
