- Added histogram-based color correction to `face_swapper.py` for improved color matching of the swapped face to the target frame. Controlled by `--color-correction`.
- Integrated Poisson blending (`cv2.seamlessClone`) for smoother face integration, reducing visible seams. Controlled by `--poisson-blending`.
- Added global variables `use_poisson_blending` and `poisson_blending_feather_amount` and corresponding command-line arguments.
- Refined argument parsing in `core.py` for new features.
- Updated `swap_face` logic to incorporate these features and handle potential errors during blending.
- Add explicit checks for face detection results (source and target faces).
- Handle cases when face embeddings are not available, preventing AttributeError.
- Provide meaningful log messages for easier debugging in future scenarios.
