- height — Height of the face
- positionX — X position relative to the document
- positionY — Y position relative to the document
- offsetX — X position relative to the offset parent
- offsetY — Y position relative to the offset parent
- scaleX — Ratio between original image width and displayed width
- scaleY — Ratio between original image height and displayed height
- confidence — Level of confidence
-
interval — Interval (default 4)
-
minNeighbors — Minimum neighbors threshold which sets the cutoff level for discarding rectangle groups as face (default 1)
