An '''Active Appearance Model''' (AAM) is a [[Computer Vision]] algorithm for matching a [[statistical model]] of object shape and apperance to a new image.

The approach is widely used for matching and tracking faces and for [[Medical Image Interpretation]].

The algorithm uses the difference between the current estimate of appearance and the target image to drive an optimisation[[Optimization (mathematics)|optimization]] process.

By taking advantage of the [[least squares]] techniques, it can match to new images very swiftly.

It is related to the [[Active Shape Model]].
