A technology for the automatic multi-class labeling of brain electron microscopy (EM) objects needed to create large synthetic datasets. which could be used for brain cell segmentation tasks. is proposed. The main research tools were a generative diffusion AI model and a U-Net-like segmentation model. https://www.spidertattooz.com/OPI-Infinite-Shine-Combo-Base-Top-March-In-Uniform-0-5-oz-ISHRK19-p26675/
