MicroSegNet: A deep learning approach for prostate segmentation on micro-ultrasound images
- Conducted meticulous manual prostate segmentation on micro-ultrasound (micro-US) images for patients, ensuring high-quality ground truth annotations.
- As a annotator my segmentation achieved a Dice Similarity Coefficient (DSC) of 0.923, serving as a strong benchmark. MicroSegNet outperformed this with a DSC of 0.939, demonstrating its ability to achieve near-expert-level accuracy in automated prostate segmentation.
RetinaRegNet: A zero-shot approach for retinal image registration
- Conducted precise manual ground truth annotation for Laser Speckle Flowgraphy (LSFG) images, ensuring accurate point correspondences for retinal image registration and aiding in the validation of multi-modal alignment.
- RetinaRegNet achieved an AUC of 86.1% on LSFG images, demonstrating its effectiveness in aligning LSFG images for tracking eye disease progression.
