Developing AI Models for Medical Image Analysis with Efficient and Low-cost Annotations
The fast development of AI techniques has revolutionized medical image analysis for computer-assisted diagnosis and treatment systems in recent years. The success of deep learning relies highly on a large set of annotated images for training. However, annotating medical images is expensive and time-consuming, due to the large size and low contrast of medical images and limited access to experts for accurate annotation. This talk will introduce several techniques of reducing the annotation cost for developing high-performance models, especially for medical image segmentation. I will present our recent works on efficient interactive annotation, weakly supervised learning, semi-supervised learning, domain adaptation and noisy label learning for medical image segmentation. These methods have been applied to a range of tasks, such as segmentation of brain tumors, covid-19 lesions, vessels and abdominal organs.
