Foreground-Aware Dataset Distillation via Dual-Path Patch Selection

Read the original on arXiv AI →

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.

D3S2: Diffusion-Guided Dataset Distillation for Semantic Segmentation

The paper introduces D3S2, a diffusion‑guided dataset distillation framework tailored for semantic segmentation. It tackles long‑tailed class imbalance, pixel‑wise alignment, and high computational cost by first selecting class‑balanced masks and then synthesizing images with a pretrained diffusion model conditioned on those masks. Guided diffusion sampling further refines the data with segmentation‑consistency and class‑wise feature matching losses, achieving superior performance at a 1% compression rate on ADE20K and COCO‑Stuff.

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.

OD3: Optimization-free Dataset Distillation for Object Detection

OD3 introduces an optimization‑free dataset distillation framework tailored for object detection. The method first iteratively places object instances in synthesized images, then screens candidates with a pre‑trained observer model to discard low‑confidence objects. Applied to MS COCO and PASCAL VOC, OD3 achieves compression ratios from 0.25% to 5% and surpasses previous detection‑focused distillation methods by over 14% on COCO mAP50 at a 1.0% compression ratio.
