# UAVid dataset configuration for Ultralytics YOLO semantic segmentation
#
# Format: https://docs.ultralytics.com/datasets/semantic/
# Masks:  single-channel PNG, pixel value = class index (0-7). 255 remains reserved
#         for genuinely unrecognized colours (e.g. corrupted/anti-aliased pixels) —
#         all 8 defined UAVid classes, including Clutter, are valid and used in both
#         training and evaluation, per the original UAVid paper.
#
# Pre-processing required
# -----------------------
# UAVid distributes 3-channel RGB colour-coded labels (Labels/ directory).
# Convert them to YOLO single-channel format first:
#
#   python src/scripts/convert_uavid_to_yolo.py \
#       --src /path/to/uavid \
#       --dst /path/to/uavid_yolo \
#       --info configs/UAVid_info.json \
#       --split both
#
# Then set the ``path`` field below to /path/to/uavid_yolo.
#
# Class mapping (all 8 classes are valid; none are ignored)
# -----------------------------------------------------------

# Root path. Ultralytics parses this file with plain YAML (no Hydra/OmegaConf

# your machine, or point `data=` at a copy of this file with your own path.
