DuetSVG: Unified Multimodal SVG Generation with Internal Visual Guidance

CVPR 2026

Recent vision-language model (VLM)-based approaches have achieved impressive results on SVG generation. However, because they generate only text and lack visual signals during decoding, they often struggle with complex semantics and fail to produce visually appealing or geometrically coherent SVGs.

Rethinking Prompt Design for Inference-time Scaling in Text-to-Visual Generation

CVPR 2026

Achieving precise alignment between user intent and generated visuals remains a central challenge in text-to-visual generation, as a single attempt often fails to produce the desired output. To handle this, prior approaches mainly scale the visual generation process (e.g., increasing sampling steps

VectorArk: Learning Practical Image Vectorization with Rounded Polygon Representation

CVPR 2026

Recent vision-language model (VLM)-based approaches have achieved impressive results on image vectorization tasks. However, they are typically evaluated on synthetic benchmarks, where clean SVGs are rasterized at high resolution and then re-vectorized. As a result, these methods generalize poorly to

DOLLAR: Few-Step Video Generation via Distillation and Latent Reward Optimization

ICCV 2025poster

Diffusion probabilistic models have shown significant progress in video generation; however, their computational efficiency is limited by the large number of sampling steps required. Reducing sampling steps often compromises video quality or generation diversity. In this work, we introduce a distill…

VideoGigaGAN: Towards Detail-rich Video Super-Resolution

CVPR 2025poster

Video super-resolution (VSR) models achieve temporal consistency but often produce blurrier results than their image-based counterparts due to limited generative capacity. This prompts the question: can we adapt a generative image upsampler for VSR while preserving temporal consistency? We introduce…

Visual Persona: Foundation Model for Full-Body Human Customization

CVPR 2025poster

We introduce Visual Persona, a foundation model for text-to-image full-body human customization that, given a single in-the-wild human image, generates diverse images of the individual guided by text descriptions. Unlike prior methods that focus solely on preserving facial identity, our approach cap…

Attention-Driven Training-Free Efficiency Enhancement of Diffusion Models

CVPR 2024poster

Diffusion models (DMs) have exhibited superior performance in generating high-quality and diverse images. However this exceptional performance comes at the cost of expensive generation process particularly due to the heavily used attention module in leading models. Existing works mainly adopt a retr…

HARIVO: Harnessing Text-to-Image Models for Video Generation

ECCV 2024poster

"We present a method to create diffusion-based video models from pretrained Text-to-Image (T2I) models. Recently, AnimateDiff proposed freezing the T2I model while only training temporal layers. We advance this method by proposing a unique architecture, incorporating a mapping network and frame-wise…

LRM: Large Reconstruction Model for Single Image to 3D

ICLR 2024oral

We propose the first Large Reconstruction Model (LRM) that predicts the 3D model of an object from a single input image within just 5 seconds. In contrast to many previous methods that are trained on small-scale datasets such as ShapeNet in a category-specific fashion, LRM adopts a highly scalable t…
