Title: Region in Context: Text-Conditioned Image Editing with Human-Like Semantic Reasoning
Primary area: generative models
Keywords: Semantic Image Editing, Denoising Diffusion Probabilistic Model

Abstract: Recent research has made significant progress in localizing and editing image regions based on text. However, most approaches treat these regions in isolation, relying solely on local cues without accounting for how each part contributes to the overall visual and semantic composition. This often results in inconsistent edits, unnatural transitions, or loss of coherence across the image. In this work, we propose Region in Context, a novel framework for text-conditioned image editing that performs multilevel semantic alignment between vision and language, inspired by the human ability to reason about edits concerning the whole scene. Our method encourages each region to understand its role within the global image context, enabling precise and harmonized changes. At its core, the framework introduces a dual-level guidance mechanism: regions are represented with full-image context and aligned with detailed region-level descriptions, while the entire image is simultaneously matched to a comprehensive scene-level description generated by a large vision-language model. These descriptions serve as explicit verbal references to the intended content, guiding both local modifications and global structure. Experiments show that it produces more coherent and instruction-aligned results.
