An Interface for Input the Object Region Using the Hand Chroma Key

摘要

We are developing the mobile system to identify wild flowers and grasses mainly from object images captured by a camera in the outdoor scene. In such systems, it is essential to inform the system an object region that the user interested in by some way. For example, if the captured image contains multiple leaves, the system can not determine which is the target leaf. In this paper, we propose interactive technique to inform the object region by placing hand behind the object. The system detects that situation, and extracts the object region automatically. Using this technique, a user can inform the system the object region in the interactive response time. Furthermore this input way is considered as natural because we often do this action to watch the object closely.
