what method two conditional area

My Project

Camera => Face Tracking (Output Ellipse) => Face Pixelate

I want smile face.

My camera is not mirroring.

But face tracking library is mirroring.

Face pixelate based in camera data. (not mirrored)

I used scale code for match.

but pixelate area error.

I hope that matchpixelate area (black area) matched yellow ellipse area.

help me.
