DiTailed: Ensuring Visual Object Consistency in Text-Image-to-Image Flow Matching Models

Francesco Taioli, Daniel Coelho, Iaroslav Melekhov, Roberto Alcover-Couso, Jose Miguel Grande Saiz, Virginia Fernandez Arguedas, Artur Bekasov

Despite remarkable progress in text-guided image editing, generative models frequently fail to preserve visual object consistency, defined as the preservation of a subject's key attributes throughout the editing process. We address this limitation through three contributions. First, we introduce ABO-Edit, a dataset specifically designed to study object consistency, comprising over 12,000 triplets of source images, editing prompts, and high-quality target images rendered from artist-designed 3D assets, with multi-view coverage and human-verified quality control. Second, we uncover an overlooked property of image-editing rectified flow models: the conditioning embedding space, not directly supervised during training, encodes a prediction of the final generated image even at high noise levels. Third, exploiting this finding, we propose FlowMirror, a parameter-free auxiliary loss that supervises this conditioning embedding space. Without architectural changes, our method improves generation quality across several metrics over baselines.

ExPLoRe: Expert Patch-Level Loss Routing for Multi-Objective Masked Image Modeling

Konstantinos Georgiou, Maofeng Tang, Hairong Qi

Multi-objective masked image modeling (MIM) combines complementary learning signals (token distillation, CLS alignment, and pixel reconstruction) but existing methods weight these objectives with global scalars, ignoring spatial heterogeneity across patches. We present ExPLoRe (E…

MixDiffusion: Mixing Diffusion-based Uni-condition Text-to-Image Generation Models for Multi-condition Image Synthesis

Pengcheng Wan, Liang Han, Lin Xu, Bowen Xiao, Liqiang Nie

Recent advances in text-to-image (T2I) generation have enabled controllable image synthesis by incorporating conditions beyond text. However, most existing diffusion-based methods are limited to a single type of control condition (e.g., bounding boxes or keypoints), which restric…

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

Zanyi Wang, Xin Lin, Haodong Li, Dengyang Jiang, Yijiang Li

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…
