Sparse Supervision for Remote Sensing Segmentation

Semantic segmentation of satellite images with minimal labeled data.

Developed a semantic segmentation model for satellite imagery under sparse supervision.

  • Built a DeepLabV3+ model with ResNet-50 as the backbone.
  • Trained using Partial Cross-Entropy Loss to handle sparse point annotations.
  • Achieved 0.43 mean Intersection over Union (mIoU) with only 1% labeled data.
  • Conducted experiments at multiple label densities (1%, 5%, 10%) to assess performance scaling.
  • Used DeepGlobe dataset and visualized segmentation outputs under low annotation settings.
