In this paper, we describe a robotic wheelchair system as guide robot To build a smart interface for a guide robot, it is important for the system to know the user's attention. This system can detect gaze direction of the user using a real-time stereo vision system, and can recognize its position within the surrounding environment using a range sensor and a(More)
Human interfaces are usually designed t o r espond only to intentional human behaviors. However, humans show unintentional behaviors as well. They can convey useful information to realize user-friendly human interfaces. This paper presents two human interface systems using both types of behaviors: a gesture-based interface and an intelligent wheelchair. In(More)
Cancer research has been an interesting and challenging research area in the field of medical science. Classification techniques have been found useful in early diagnosis of cancer and better treatment. For diagnosis of cancer various classification methods are used but they suffer with one or more disadvantages. In this paper ensemble based classification(More)
Since conventional correlation-based visual tracking algorithms are based on a single reference block, they often fail to track a target in the following situations: 1) a view of the target image changes, and 2) a part of the target image is occluded. This paper proposes a correlation-based visual tracking method which copes with these problems based on ane(More)
