Beyond Spatio-Temporal Priors: A Generalizable Approach for Dense Correspondence Matching

The paper introduces FreeMatching, a framework that moves beyond traditional spatio-temporal priors for dense correspondence matching. It combines generative and semantic representations with diverse supervision sources, and uses teacher‑guided refinement to improve identity‑preserving correspondence in image editing and reference‑guided generation tasks. Experiments show that a single FreeMatching model outperforms existing methods on challenging image pairs while maintaining strong performance on classical benchmarks, and its scores correlate with human judgment of identity preservation.

DuoMatching: Joint-Marginal Distribution Matching for Few-Step Video Generation

DuoMatching is a new framework for few-step video generation that extends distribution matching distillation by adding a joint‑marginal formulation. It introduces a marginal matching objective that uses an image generator to provide frame‑level supervision, and employs LatentBridge to align latent representations between the video student and image teacher. Latent Variation Sampling distributes this supervision across temporal segments, improving visual quality, composition, and semantic alignment while preserving motion dynamics, with human evaluations favoring it over baselines.

RefVideo-6M: A Reliable Reference-Based Dataset for Instructional Video Editing

RefVideo-6M is a new large-scale reference-guided editing dataset that includes 5 million video editing samples and 1 million image editing samples, each paired with about 6 million visual references. The dataset is constructed to avoid artifacts by using real, artifact‑free videos as targets and filtering input conditions with multiple editing experts, thereby providing reliable supervision. It enables models to learn fine‑grained visual correspondence beyond text‑only instructions and supports the training of a reference‑guided video editing model, Ref‑MoT, which shows improved visual quality, controllability, and reference consistency.

CogCanvas: A Benchmark for Evaluating Multi-Subject Reference-Based Image Generation

CogCanvas is a new benchmark for multi-subject reference-based image generation, featuring 1,952 curated reference images of 100 celebrities, 115 objects/fashion items, and 29 real-world backgrounds. It generates 1,361 compositional prompts with 2–5 people, using a pipeline that includes DINOv2 deduplication, aesthetic filtering, and automated graph derivation for interaction and positioning. The benchmark evaluates three tasks—reference-based multi-human-object generation, text-to-image compositional generation, and reference retrieval—under a six-axis protocol, and introduces BG‑Sim and Attr‑VQA metrics to assess background fidelity and attribute binding.

CameraEditor: Camera-Controlled Image Editing via Video-Prior Sequential Modeling

CameraEditor is a new framework that transforms camera-controlled image editing into a temporal sequence prediction problem. By using video diffusion models, it incorporates a geometric perception module and dynamic reference routing to create precise visual references through dynamic panorama cropping. The method also inserts intermediate transition frames to handle large perspective shifts, maintaining content identity and spatial coherence, and is evaluated on a dataset of 5,760 instances with a benchmark of 462 test cases, achieving state‑of‑the‑art performance.
