Orientation-Guided Graph Convolutional Network for Bone Surface Segmentation
Authors : Aimon Rahman , WGC Bandara, Jeya Maria Jose Valanarasu, Ilker Hacihaliloglu, Vishal M Patel
MICCAI, 2022  
The article proposes a new method for bone surface segmentation using an orientation-guided graph convolutional network to improve connectivity in ultrasound images. The approach also adds supervision on the orientation of the bone surface to further impose connectivity. Validation on over 1000 in vivo US scans shows a 5.01% improvement over state-of-the-art methods in connectivity metric.

Simultaneous Bone and Shadow Segmentation Network Using Task Correspondence Consistency
Authors : Aimon Rahman , Jeya Maria Jose Valanarasu, Ilker Hacihaliloglu, Vishal M Patel
MICCAI, 2022  
The article proposes a new approach for segmenting both bone surface and the corresponding acoustic shadow in ultrasound images using a single end-to-end network with a shared transformer-based encoder and task independent decoders. The approach leverages the complementary features between the two tasks and includes a cross-task feature transfer block to learn meaningful feature transfer between the two decoders.

Leaderboard (2nd place)
We pretrain a model on videos for human activity recognition which leads to better
representations for the downstream tuberculosis type classification task, especially for under-represented class samples.
Our method achieved 2nd place in the ImageCLEF 2021

Dataset /
Code
This work proposes a blood cell segmentation dataset consisting of multiple cell types.
Additionally, all cell types
do not have equal instances, which encourages researchers to develop algorithms for
learning from imbalanced classes in a few shot learning paradigm. We also provide both learning and non-learning based
methods as baselines.
