Use this skill for work on feature tracking, dense optical flow, DIS/TV-L1, transform fitting, smoothing, crop handling, or fallback behavior.
cv2.optflow is not available in standard OpenCV wheels; TV-L1 requires contrib
OpenCV or an equivalent available API.cv2 or cv2.optflow exists unless declared and checked.flow_backend, applied transform mode,
confidence/residual data where available).python3 scripts/validate_repo.py
python3 -c "import cv2; print(cv2.__version__, hasattr(cv2, 'DISOpticalFlow'), hasattr(cv2, 'optflow'))"
If using a ComfyUI venv, run the cv2 check inside that venv too.
