| Summary: | Gesture recognition represents an important ability by which a computer is able to
directly accept human gesture as input to trigger different actions just like
conventional input devices such as keyboard. mouse, joystick and etc. As the Human
Computer Interaction (HCI) progresses over the years, emphasis is placed more on
developing input devices which are most convenient and easy to use. Human gesture
is not only natural and intuitive to a user, but can also represent motions of high
degree of freedom which is of utmost importance in many applications especially in
virtual reality.
This thesis presents the design of an offline system which is capable of recognizing
hand postures from the visual input of a web camera. The hand segmentation is based
on image subtraction technique and a skin color modeling process. Fourier descriptors are used as the features to describe the geometry of different hand
postures while the recognition process is based on minimum distance classifier. The
results obtained indicate that the system is able to recognize hand postures with
reasonable accuracy |
