Filtered-Guided Diffusion: Fast Filter Guidance for Black-Box Diffusion Models

1 code implementation29 Jun 2023 Zeqi Gu, Abe Davis

In this work, we show that much of this low-level control can be achieved without additional training or any access to features of the diffusion model.

FactorMatte: Redefining Video Matting for Re-Composition Tasks

no code implementations3 Nov 2022 Zeqi Gu, Wenqi Xian, Noah Snavely, Abe Davis

Based on this observation, we present a method for solving the factor matting problem that produces useful decompositions even for video with complex cross-layer interactions like splashes, shadows, and reflections.

Robotic Dough Shaping

1 code implementation31 Jul 2022 Jan Ondras, Di Ni, Xi Deng, Zeqi Gu, Henry Zheng, Tapomayukh Bhattacharjee

The ability to deform soft objects remains a great challenge for robots due to difficulties in defining the problem mathematically.

Measuring Dataset Granularity

1 code implementation21 Dec 2019 Yin Cui, Zeqi Gu, Dhruv Mahajan, Laurens van der Maaten, Serge Belongie, Ser-Nam Lim

We also investigate the interplay between dataset granularity with a variety of factors and find that fine-grained datasets are more difficult to learn from, more difficult to transfer to, more difficult to perform few-shot learning with, and more vulnerable to adversarial attacks.

Enhancing Adversarial Example Transferability with an Intermediate Level Attack

2 code implementations ICCV 2019 Qian Huang, Isay Katsman, Horace He, Zeqi Gu, Serge Belongie, Ser-Nam Lim

We show that we can select a layer of the source model to perturb without any knowledge of the target models while achieving high transferability.
