From subfolder (self-contained):
# OV-2 with AlignEarth (SAR)
from pipeline import SegEarthPipeline
pipe = SegEarthPipeline() # loads OV-2/config.json
seg = pipe(image)
# Or: cd OV-2 && python -c "from pipeline import load; pipe = load()"
From repo root:
from pipeline import SegEarthPipeline
pipe = SegEarthPipeline(variant="OV-2")
pipe = SegEarthPipeline(variant="OV")
pipe = SegEarthPipeline(variant="OV-3") # requires sam3 package
Custom class config:
pipe = SegEarthPipeline(variant="OV-2", class_names_path="OV-2/configs/cls_yeseg_sar.txt")
