HAPRec: Hybrid Activity and Plan Recognizer
  Computer-based assistants have recently attracted much interest due to its
applicability to ambient assisted living. Such assistants have to detect and
recognize the high-level activities and goals performed by the assisted human
beings. In this work, we demonstrate activity recognition in an indoor
environment in order to identify the goal towards which the subject of the
video is pursuing. Our hybrid approach combines an action recognition module
and a goal recognition algorithm to identify the ultimate goal of the subject
in the video.
