Show from Tell: Audio-Visual Modelling in Clinical Settings

no code implementations25 Oct 2023 Jianbo Jiao, Mohammad Alsharid, Lior Drukker, Aris T. Papageorghiou, Andrew Zisserman, J. Alison Noble

Auditory and visual signals usually present together and correlate with each other, not only in natural environments but also in clinical settings.

Anatomy-Aware Contrastive Representation Learning for Fetal Ultrasound

1 code implementation22 Aug 2022 Zeyu Fu, Jianbo Jiao, Robail Yasrab, Lior Drukker, Aris T. Papageorghiou, J. Alison Noble

The proposed approach is demonstrated for automated fetal ultrasound imaging tasks, enabling the positive pairs from the same or different ultrasound scans that are anatomically similar to be pulled together and thus improving the representation learning.

Multimodal-GuideNet: Gaze-Probe Bidirectional Guidance in Obstetric Ultrasound Scanning

no code implementations26 Jul 2022 Qianhui Men, Clare Teng, Lior Drukker, Aris T. Papageorghiou, J. Alison Noble

To understand the causal relationship between gaze movement and probe motion, our model exploits multitask learning to jointly learn two related tasks: predicting gaze movements and probe signals that an experienced sonographer would perform in routine obstetric scanning.

Self-supervised Contrastive Video-Speech Representation Learning for Ultrasound

no code implementations14 Aug 2020 Jianbo Jiao, Yifan Cai, Mohammad Alsharid, Lior Drukker, Aris T. Papageorghiou, J. Alison Noble

For this case, we assume that there is a high correlation between the ultrasound video and the corresponding narrative speech audio of the sonographer.

Automatic Probe Movement Guidance for Freehand Obstetric Ultrasound

no code implementations8 Jul 2020 Richard Droste, Lior Drukker, Aris T. Papageorghiou, J. Alison Noble

Evaluations for 3 standard plane types show that the model provides a useful guidance signal with an accuracy of 88. 8% for goal prediction and 90. 9% for action prediction.

Ultrasound Image Representation Learning by Modeling Sonographer Visual Attention

no code implementations7 Mar 2019 Richard Droste, Yifan Cai, Harshita Sharma, Pierre Chatelain, Lior Drukker, Aris T. Papageorghiou, J. Alison Noble

Secondly, we train a simple softmax regression on the feature activations of each CNN layer in order to evaluate the representations independently of transfer learning hyper-parameters.
