New backpropagation-free framework for thyroid nodule segmentation

By PulseAugur Editorial · [2 sources] ·

Researchers have developed MedSaab-US, a novel framework for segmenting thyroid nodules in ultrasound images that does not rely on backpropagation or deep learning. This approach combines multi-level Discrete Wavelet Transform with multi-scale Saab transforms to extract features, which are then processed by an XGBoost classifier. MedSaab-US achieves a mean Dice coefficient of 0.4784 on the TN3K dataset, with a small model footprint and CPU-only inference capabilities, offering a potential alternative for resource-constrained environments.
