Videoshop: Localized Semantic Video Editing with Noise-Extrapolated Diffusion Inversion

no code implementations21 Mar 2024 Xiang Fan, Anand Bhattad, Ranjay Krishna

We introduce Videoshop, a training-free video editing algorithm for localized semantic edits.

Generative Models: What do they know? Do they know things? Let's find out!

no code implementations28 Nov 2023 Xiaodan Du, Nicholas Kolkin, Greg Shakhnarovich, Anand Bhattad

Generative models have been shown to be capable of synthesizing highly detailed and realistic images.

Improving Equivariance in State-of-the-Art Supervised Depth and Normal Predictors

1 code implementation ICCV 2023 Yuanyi Zhong, Anand Bhattad, Yu-Xiong Wang, David Forsyth

Dense depth and surface normal predictors should possess the equivariant property to cropping-and-resizing -- cropping the input image should result in cropping the same output image.

Blocks2World: Controlling Realistic Scenes with Editable Primitives

no code implementations7 Jul 2023 Vaibhav Vavilala, Seemandhar Jain, Rahul Vasanth, Anand Bhattad, David Forsyth

We present Blocks2World, a novel method for 3D scene rendering and editing that leverages a two-step process: convex decomposition of images and conditioned synthesis.

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.

StyLitGAN: Prompting StyleGAN to Produce New Illumination Conditions

no code implementations20 May 2022 Anand Bhattad, D. A. Forsyth

We propose a novel method, StyLitGAN, for relighting and resurfacing generated images in the absence of labeled data.

SIRfyN: Single Image Relighting from your Neighbors

no code implementations8 Dec 2021 D. A. Forsyth, Anand Bhattad, Pranav Asthana, Yuanyi Zhong, YuXiong Wang

Novel theory shows that one can use similar scenes to estimate the different lightings that apply to a given scene, with bounded expected error.

View Generalization for Single Image Textured 3D Models

no code implementations CVPR 2021 Anand Bhattad, Aysegul Dundar, Guilin Liu, Andrew Tao, Bryan Catanzaro

We describe a cycle consistency loss that encourages model textures to be aligned, so as to encourage sharing.

Cut-and-Paste Object Insertion by Enabling Deep Image Prior for Reshading

no code implementations12 Oct 2020 Anand Bhattad, David A. Forsyth

We show how to insert an object from one image to another and get realistic results in the hard case, where the shading of the inserted object clashes with the shading of the scene.

Improving Style Transfer with Calibrated Metrics

1 code implementation21 Oct 2019 Mao-Chuang Yeh, Shuai Tang, Anand Bhattad, Chuhang Zou, David Forsyth

Style transfer methods produce a transferred image which is a rendering of a content image in the manner of a style image.

Unrestricted Adversarial Examples via Semantic Manipulation

1 code implementation ICLR 2020 Anand Bhattad, Min Jin Chong, Kaizhao Liang, Bo Li, D. A. Forsyth

Machine learning models, especially deep neural networks (DNNs), have been shown to be vulnerable against adversarial examples which are carefully crafted samples with a small magnitude of the perturbation.

Quantitative Evaluation of Style Transfer

no code implementations31 Mar 2018 Mao-Chuang Yeh, Shuai Tang, Anand Bhattad, D. A. Forsyth

Style transfer methods produce a transferred image which is a rendering of a content image in the manner of a style image.

Detecting Anomalous Faces with 'No Peeking' Autoencoders

no code implementations15 Feb 2018 Anand Bhattad, Jason Rock, David Forsyth

We describe a method for detecting an anomalous face image that meets these requirements.
