Local Relighting of Real Scenes

2 code implementations6 Jul 2022 Audrey Cui, Ali Jahanian, Agata Lapedriza, Antonio Torralba, Shahin Mahdizadehaghdam, Rohit Kumar, David Bau

We introduce the task of local relighting, which changes a photograph of a scene by switching on and off the light sources that are visible within the image.

Exploring Visual Prompts for Adapting Large-Scale Models

1 code implementation31 Mar 2022 Hyojin Bahng, Ali Jahanian, Swami Sankaranarayanan, Phillip Isola

The surprising effectiveness of visual prompting provides a new perspective on adapting pre-trained models in vision.

Generative Models as a Data Source for Multiview Representation Learning

1 code implementation ICLR 2022 Ali Jahanian, Xavier Puig, Yonglong Tian, Phillip Isola

We investigate this question in the setting of learning general-purpose visual representations from a black-box generative model rather than directly from data.

Instance Semantic Segmentation Benefits from Generative Adversarial Networks

1 code implementation26 Oct 2020 Quang H. Le, Kamal Youcef-Toumi, Dzmitry Tsetserukou, Ali Jahanian

Rethinking reconstruction networks as a generator, we define the problem of predicting masks as a GANs game framework: A segmentation network generates the masks, and a discriminator network decides on the quality of the masks.

On the "steerability" of generative adversarial networks

2 code implementations16 Jul 2019 Ali Jahanian, Lucy Chai, Phillip Isola

We hypothesize that the degree of distributional shift is related to the breadth of the training data distribution.
