Abstract: Highlights•A dual-branch network with dynamically mixed pseudo-labels for scribble-supervised segmentation.•Soft pseudo-label supervision is used to alleviate the effect of noisy pseudo-labels.•An uncertainty-based annotation expansion strategy to handle unlabeled regions.•Our method was more robust than state-of-the-art methods under extremely sparse scribbles.
