Mitigating Content Shift and Hallucination in GenAI Image Editing via Structural Refinement
Luxi Zhao, Michael S. Brown
Generative AI (GenAI) image editors, such as Nano Banana, produce visually compelling results for retouching tasks, enabling non-experts to edit images through text prompts alone.…
Addressing Image Authenticity When Cameras Use Generative AI
Umar Masud, Abhijith Punnappurath, Luxi Zhao +2
The ability of generative AI (GenAI) methods to photorealistically alter camera images has raised awareness about the authenticity of images shared online. Interestingly, images ca…
Edit-aware RAW Reconstruction
Abhijith Punnappurath, Luxi Zhao, Ke Zhao +3
Users frequently edit camera images post-capture to achieve their preferred photofinishing style. While editing in the RAW domain provides greater accuracy and flexibility, most ed…
Improved Mapping Between Illuminations and Sensors for RAW Images
Abhijith Punnappurath, Luxi Zhao, Hoang Le +3
RAW images are unprocessed camera sensor output with sensor-specific RGB values based on the sensor's color filter spectral sensitivities. RAW images also incur strong color casts…
Learning Camera-Agnostic White-Balance Preferences
Luxi Zhao, Mahmoud Afifi, Michael S. Brown
The image signal processor (ISP) pipeline in modern cameras consists of several modules that transform raw sensor data into visually pleasing images in a display color space. Among…
Examining Joint Demosaicing and Denoising for Single-, Quad-, and Nona-Bayer Patterns
SaiKiran Tedla, Abhijith Punnappurath, Luxi Zhao +1
Camera sensors have color filters arranged in a mosaic layout, traditionally following the Bayer pattern. Demosaicing is a critical step camera hardware applies to obtain a full-ch…
