Vision-Language Models Enhance XRF-to-Optical Microscopy Localization

Researchers have developed a new method for localizing images taken with different microscopy modalities, specifically X-ray fluorescence (XRF) and optical microscopy. This is crucial for correlating complementary measurements of the same specimen, especially when the XRF map covers only a small portion of the optical image. The study evaluates vision-language models (VLMs) for this task, comparing them against geometric controls, template matching, and other training-free approaches. A proposal-and-verify workflow using VLM predictions as candidates and image similarity for selection proved effective, particularly in low-correspondence scenarios where structural differences between modalities are significant.
