2025 HD-Painter: High-Resolution and Prompt-Faithful Text-Guided Image Inpainting with Diffusion Models
abstract
Recent progress in text-guided image inpainting, based on the unprecedented success of text-to-image diffusion models, has led to exceptionally realistic and visually plausible results. However, there is still significant potential for improvement in current text-to-image inpainting models, particularly in better aligning the inpainted area with user prompts. Therefore, we introduce $\textit{HD-Painter}$, a $\textbf{training-free}$ approach that $\textbf{accurately follows prompts}$. To this end, we design the $\textit{Prompt-Aware Introverted Attention (PAIntA)}$ layer enhancing self-attention scores by prompt information resulting in better text aligned generations. To further improve the prompt coherence we introduce the $\textit{Reweighting Attention Score Guidance (RASG)}$ mechanism seamlessly integrating a post-hoc sampling strategy into the general form of DDIM to prevent out-of-distribution latent shifts. Our experiments demonstrate that HD-Painter surpasses existing state-of-the-art approaches quantitatively and qualitatively across multiple metrics and a user study.

2024 Continuous Adaptation for Interactive Segmentation Using Teacher-Student Architecture
abstract
Interactive segmentation is the task of segmenting objects or regions of interest from images based on user annotations. While most current methods perform effectively on images from the same distribution as the training dataset, they suffer to generalize on unseen domains. To address this issue some approaches incorporate test-time adaptation techniques which, on the other hand, may lead to catastrophic forgetting (i.e. degrading the performance on the previously seen domains) when applied on datasets from various domains sequentially. In this paper, we propose a novel domain adaptation approach leveraging a teacher-student learning framework to tackle the catastrophic forgetting issue. Continuously updating the student and teacher models based on user clicks results in improved segmentation accuracy on unseen domains, while preserving comparable performance on previous domains. Our approach is evaluated on a sequence of datasets from unseen domains (i.e. medical, aerial images, etc.), and, after adaptation, on the source domain demonstrating a significant decline of catastrophic forgetting (e.g. from 55% to 4% on Berkeley dataset).
