| Active System To Generate Views Of Facial Features With Selectable Resolution (2007) | |||||||||||||||
Abstract | |||||||||||||||
| In many applications concerning the analysis of a human face or of facial features, images with selectable resolutions are desirable. The first step of our system is the detection of facial features. We present a parametric face model for localization and evaluate the model by an energy minimization process. To change the resolution selected by the user, we need a camera with a calibrated zooming unit. We present a method to calibrate the zoom unit of a camera with pan/tilt unit. The advantage of the approach is that the focal length can be related to the stepper motor setting without any calibration pattern or knowledge about the scene. 1 | |||||||||||||||
