Street TryOn: Learning In-the-Wild Virtual Try-On from Unpaired Person Images

1 code implementation27 Nov 2023 Aiyu Cui, Jay Mahajan, Viraj Shah, Preeti Gomathinayagam, Svetlana Lazebnik

By contrast, it is hard to collect paired data for in-the-wild scenes, and therefore, virtual try-on for casual images of people against cluttered backgrounds is rarely studied.

ZipLoRA: Any Subject in Any Style by Effectively Merging LoRAs

1 code implementation22 Nov 2023 Viraj Shah, Nataniel Ruiz, Forrester Cole, Erika Lu, Svetlana Lazebnik, Yuanzhen Li, Varun Jampani

Experiments on a wide range of subject and style combinations show that ZipLoRA can generate compelling results with meaningful improvements over baselines in subject and style fidelity while preserving the ability to recontextualize.

JoIN: Joint GANs Inversion for Intrinsic Image Decomposition

no code implementations18 May 2023 Viraj Shah, Svetlana Lazebnik, Julien Philip

In this work, we propose to solve ill-posed inverse imaging problems using a bank of Generative Adversarial Networks (GAN) as a prior and apply our method to the case of Intrinsic Image Decomposition for faces and materials.

Make It So: Steering StyleGAN for Any Image Inversion and Editing

no code implementations27 Apr 2023 Anand Bhattad, Viraj Shah, Derek Hoiem, D. A. Forsyth

StyleGAN's disentangled style representation enables powerful image editing by manipulating the latent variables, but accurately mapping real-world images to their latent variables (GAN inversion) remains a challenge.

MultiStyleGAN: Multiple One-shot Image Stylizations using a Single GAN

no code implementations8 Oct 2022 Viraj Shah, Ayush Sarkar, Sudharsan Krishnakumar Anitha, Svetlana Lazebnik

Recent approaches for one-shot stylization such as JoJoGAN fine-tune a pre-trained StyleGAN2 generator on a single style reference image.

Near Perfect GAN Inversion

no code implementations23 Feb 2022 Qianli Feng, Viraj Shah, Raghudeep Gadde, Pietro Perona, Aleix Martinez

To edit a real photo using Generative Adversarial Networks (GANs), we need a GAN inversion algorithm to identify the latent vector that perfectly reproduces it.

CloudFindr: A Deep Learning Cloud Artifact Masker for Satellite DEM Data

no code implementations26 Oct 2021 Kalina Borkiewicz, Viraj Shah, J. P. Naiman, Chuanyue Shen, Stuart Levy, Jeff Carpenter

Artifact removal is an integral component of cinematic scientific visualization, and is especially challenging with big datasets in which artifacts are difficult to define.

TweeNLP: A Twitter Exploration Portal for Natural Language Processing

no code implementations ACL 2021 Viraj Shah, Shruti Singh, Mayank Singh

It supports multiple features such as TweetExplorer to explore tweets by topics, visualize insights from Twitter activity throughout the organization cycle of conferences, discover popular research papers and researchers.

Provably Convergent Algorithms for Solving Inverse Problems Using Generative Models

no code implementations13 May 2021 Viraj Shah, Rakib Hyder, M. Salman Asif, Chinmay Hegde

The traditional approach of hand-crafting priors (such as sparsity) for solving inverse problems is slowly being replaced by the use of richer learned priors (such as those modeled by deep generative networks).

Encoding Invariances in Deep Generative Models

no code implementations4 Jun 2019 Viraj Shah, Ameya Joshi, Sambuddha Ghosal, Balaji Pokuri, Soumik Sarkar, Baskar Ganapathysubramanian, Chinmay Hegde

Reliable training of generative adversarial networks (GANs) typically require massive datasets in order to model complicated distributions.

Alternating Phase Projected Gradient Descent with Generative Priors for Solving Compressive Phase Retrieval

no code implementations7 Mar 2019 Rakib Hyder, Viraj Shah, Chinmay Hegde, M. Salman Asif

We empirically show that the performance of our method with projected gradient descent is superior to the existing approach for solving phase retrieval under generative priors.

Signal Reconstruction from Modulo Observations

1 code implementation3 Dec 2018 Viraj Shah, Chinmay Hegde

We consider the problem of reconstructing a signal from under-determined modulo observations (or measurements).

Physics-aware Deep Generative Models for Creating Synthetic Microstructures

no code implementations21 Nov 2018 Rahul Singh, Viraj Shah, Balaji Pokuri, Soumik Sarkar, Baskar Ganapathysubramanian, Chinmay Hegde

The first model is a WGAN model that uses a finite number of training images to synthesize new microstructures that weakly satisfy the physical invariances respected by the original data.

Solving Linear Inverse Problems Using GAN Priors: An Algorithm with Provable Guarantees

1 code implementation23 Feb 2018 Viraj Shah, Chinmay Hegde

In this work, we advocate the idea of replacing hand-crafted priors, such as sparsity, with a Generative Adversarial Network (GAN) to solve linear inverse problems such as compressive sensing.
