GenDeg: Diffusion-based Degradation Synthesis for Generalizable All-In-One Image Restoration

CVPR 2025poster

Deep learning-based models for All-In-One image Restoration (AIOR) have achieved significant advancements in recent years. However, their practical applicability is limited by poor generalization to samples outside the training distribution. This limitation arises primarily from insufficient diversi…

Scaling Transformer-Based Novel View Synthesis with Models Token Disentanglement and Synthetic Data

ICCV 2025poster

Large transformer-based models have made significant progress in generalizable novel view synthesis (NVS) from sparse input views, generating novel viewpoints without the need for test-time optimization. However, these models are constrained by the limited diversity of publicly available scene datas…

CrowdDiff: Multi-hypothesis Crowd Density Estimation using Diffusion Models

CVPR 2024poster

Crowd counting is a fundamental problem in crowd analysis which is typically accomplished by estimating a crowd density map and summing over the density values. However this approach suffers from background noise accumulation and loss of density due to the use of broad Gaussian kernels to create the…

Steered Diffusion: A Generalized Framework for Plug-and-Play Conditional Image Synthesis

ICCV 2023poster

Conditional generative models typically demand large annotated training sets to achieve high-quality synthesis. As a result, there has been significant interest in designing models that perform plug-and-play generation, i.e., to use a predefined or pretrained model, which is not explicitly trained o…

Unite and Conquer: Plug & Play Multi-Modal Synthesis Using Diffusion Models

CVPR 2023poster

Generating photos satisfying multiple constraints finds broad utility in the content creation industry. A key hurdle to accomplishing this task is the need for paired data consisting of all modalities (i.e., constraints) and their corresponding output. Moreover, existing methods need retraining usin…
