Intel® Perceptual Computing SDK
The Intel® Perceptual Computing SDK is a library of pattern detection and recognition algorithm implementations exposed through standardized interfaces. The SDK provides a suite of face analysis algorithms including face location detection, landmark detection, face recognition and face attribute detection.
This tutorial shows how to use the SDK for face location detection, landmark detection, and how to write an application for these face analysis modules.
