Researchers have developed AxonSynth, a novel framework that generates synthetic data for training 3D axon segmentation models. This approach aims to overcome the challenge of obtaining expensive manual annotations for microscopy data. AxonSynth creates synthetic axon labels with realistic orientation priors and renders them with randomized visual properties like density, contrast, and noise. A 3D U-Net model trained on this synthetic data demonstrated strong zero-shot transfer capabilities, outperforming traditional thresholding and filtering methods in key metrics for macaque and human brain samples.
