Abstract:Feature dimensionality plays an important role for modern medical diagnosis and image processing. In this work, the study introduces an optoelectronic neural network for multimodal image segmentation, which dramatically improves computing speed and decreases imaging acquisition cost in brain tumor diagnostics. Multi‐layer metasurfaces are utilized as an image preprocessor that reduces image dimensionality at the physical layer. The low‐dimensional image is then processed to a U‐Net semantic segmentation networ… Show more
