Chameleon: Style-Content Disentangled Framework for Cross-Domain Object Compositing

The paper introduces Chameleon, a two‑stage training framework for cross‑domain image compositing that separates style and content representations. It first trains a ChameleonEncoder using Joint Hard Contrastive Learning to disentangle style and content, then applies Spatio‑Temporal Attention Gating within a diffusion transformer to stylize the foreground while preserving its identity. The authors also release ChameleonDataset, the first large‑scale training set for cross‑domain compositing, and demonstrate that Chameleon outperforms existing in‑domain, cross‑domain, and commercial models in both plausibility and stylistic fidelity.

UniGP: Taming Diffusion Transformer for Prior-Preserved Unified Generation and Perception

Recent advances in diffusion models have shown impressive performance in controllable image generation and dense prediction tasks. However, existing approaches typically treat diffusion-based controllable generation and dense prediction as separate tasks, overlooking the potential benefits of jointly modeling the heterogeneous distributions.

Foreground-Aware Dataset Distillation via Dual-Path Patch Selection

The paper introduces a foreground-aware dataset distillation technique that uses a dual-path patch selection strategy. By estimating foreground occupancy with Grounded SAM2, images are routed either to a candidate-crop selection path for sparse foregrounds or a direct transformation path for dominant foregrounds, balancing foreground concentration and background reduction. Experiments on CIFAR-10, CIFAR-100, ImageNette, and ImageWoof show the method surpasses the baseline RDED across multiple architectures and distillation budgets.

UltraFlux: Data-Model Co-Design for High-quality Native 4K Text-to-Image Generation across Diverse Aspect Ratios

arXiv:2511. 18050v1 Announce Type: cross Abstract: Diffusion transformers have recently delivered strong text-to-image generation around 1K resolution, but we show that extending them to native 4K across diverse aspect ratios exposes a tightly coupled failure mode spanning positional encoding, VAE compression, and optimization.

Representation Learning via Composite Subspace Flow Matching

The paper introduces Composite Subspace Flow Matching (CSFM), a representation learning method that minimizes variance by inverting a deterministic degradation curriculum across spectral, color, and illumination subspaces. CSFM uses hard temporal style truncation to constrain an encoder, encouraging it to ignore transient style artifacts while preserving persistent content. Experiments on CIFAR-10, CIFAR-100, and STL-10 demonstrate that CSFM achieves competitive discriminative transferability and generative synthesis, outperforming standard optimal transport flows in linear probing and few‑shot classification while maintaining a smooth latent space.

From RGB Generation to Dense Field Readout: Pixel-Space Dense Prediction with Text-to-Image Models

Large-scale text-to-image models are attractive backbones for dense prediction because RGB generation pretraining learns rich semantic, structural, and geometric priors. Existing generative and editing approaches reuse these priors by casting dense prediction as target generation: annotations such as depth, normals, alpha mattes, masks, and heatmaps are encoded into an RGB-trained VAE latent space and decoded back as image-like targets.
