| description | "Motion gesture is one of the gesture recognition algorithms which provide touchless
interaction within a system. The main objective of this project is to design a system
that detects motion gesture of a virtual heart in medical imaging environment. This
project encompassesa few gesture algorithmss uch as GestureE stimation,F eedback
and Gesture Recognition. The purpose of Gesture Estimation is to detect gestures
and locates the screen coordinates. The Feedback is to produce response from the
user regarding the motion data and the position of gestures. Gesture Recognition is
to recognise the gestures and performs the basic transformation of the virtual heart.
A Predefine Offset Screen Distance for Gesture Recognition is proposed. The flow of
the algorithm can be divided into four steps. The first step is to calculate the offset
line. Second, Recognition Threshold is declared to diminish the noise of the motion.
Third, the range which is defined as left or right is used for gesture recognition.
Lastly, the basic transformation such as rotation, translation and scale is executed if
a data motion lies within the range. Four experiments are carried out to evaluate the
prototype system. The experiments are Gesture Test, Lighting Test, Distance Test
and Memory test. Besides, the proposed Predefine Offset Screen Distance is further
analysed by measuring time complexity using Big-O Notation. The results showed
that the proposed Predefine Offset Screen Distance is not very efficient and it has
higher computational cost in time complexity with 0(n2). In this study, a prototype of
Augmented Reality system that implements gesture motion is developed. The use of
the gesture motion algorithm enables an interactive environment in medical imaging. |
