Release Notes

11 Julu 2025 – DfW v1.1

• Input Video Format Update
  The required input video format has been updated from a compressed NumPy archive (*.npz) to standard video formats such as *.mov or *.mp4.

• Coordinate System Handling
  Previously, local spatial coordinates (xi, yi) were embedded within the .npz file as 2D arrays matching the video resolution. In the updated version, spatial referencing is now provided via a separate extent.txt file, formatted as: [xmin xmax ymin ymax].

• Configuration Management
  Required parameters are no longer hardcoded in init.py. All runtime configurations are now specified in a standalone config.yaml file.

• Visualization Enhancement
  Results can now be overlaid on satellite imagery using an optional basemap.png file.

• Ground Truth Input Flexibility
  Ground truth data can now be provided in multiple formats:

  • Raster-based: e.g., GeoTIFF for gridded reference surfaces.
  • Point-based: e.g., *.csv or *.xyz for point cloud data.

24 March 2025 – DfW v1.0
