We also found that the Latent Shift explanation allows a user to have more confidence in true positive predictions compared to traditional approaches (0. 15$\pm$0. 95 in a 5 point scale with p=0. 01) with only a small increase in false positive predictions (0. 04$\pm$1. 06 with p=0. 57).


Fine tuning U-Net for ultrasound image segmentation: which layers?

no code implementations19 Feb 2020 Mina Amiri, Rupert Brooks, Hassan Rivaz

In this study, we investigated the effect of fine-tuning different layers of a U-Net which was trained on segmentation of natural images in breast ultrasound image segmentation.

Breast lesion segmentation in ultrasound images with limited annotated data

no code implementations21 Jan 2020 Bahareh Behboodi, Mina Amiri, Rupert Brooks, Hassan Rivaz

Ultrasound (US) is one of the most commonly used imaging modalities in both diagnosis and surgical interventions due to its low-cost, safety, and non-invasive characteristic.
