Terminology Issues for Face Alignment and Keypoint Detection

[xieyipeng]

• This face-alignment is for face key point detection,But how should I do the real alignment operation?

• Like an affine transformation, keeping the eyes on the horizon?

• I want to know the most formal, real alignment

The terminologies are largely used interchangeable. This reflects how historically face alignment/key points detection was performed: one would take a deformable facial model and align it with an image such that the model will now match the location of a set of desired fiducial points.

A good reference for this is the work from Gu&Kanade (https://link.springer.com/referenceworkentry/10.1007/978-0-387-73003-5_186)
