Weakly Supervised Fish Segmentation through Point-Supervised Tracking and Motion-Informed Language

To address this inefficiency, we propose a weakly supervised segmentation pipeline that requires only point-labeled data (one click per fish) to produce accurate segmentation masks.

Key points

  • Understanding the properties of fish populations is increasingly important.
  • Deep learning-based segmentation models offer a promising means of obtaining such information at scale.
  • Most of these models, however, require costly and time-consuming per-pixel segmentation labels for training, which can take up to two minutes per fish to annotate manually.
  • Experiments on the DeepFish dataset show improvement in foreground mean intersection over union (mIoU) as compared to baseline models.
