| Zusammenfassung: | This tutorial introduces issues in long-range facial image acquisition and measures for image quality and their usage, as well as subsequent challenges for face recognition. The first several modules on image acquisition for face recognition discuss concerns related to lighting, sensors, and lenses, which impact short-range biometrics, but are more pronounced in long-range biometrics. We then go on to introduce the design of controlled experiments for long-range face recognition and why they are needed. With our experiments, we go on to show some of the weather and atmospheric effects that occur for long-range imaging, with numerous examples. Next, we address measurements of "system quality" including image-quality measures and their use in the prediction of face recognition algorithm performance. That module introduces the concept of post-recognition score analysis and techniques for analyzing different "equality" measures. The last two modules of this tutorial explore long-range face recognition directly. Facial feature detection is an important prerequisite for face recognition, and we look at two different approaches for accurately accomplishing this for long-range scenarios. Finally, we address the very difficult problem of blur "both motion and atmospheric" including common sources in acquisition and algorithms to mitigate its effects |
