Gesture represents a non-verbal means of communication between people. It comes from poses or movements performed by the human body. Nowadays, hand gestures are the new modality for human and computer interaction. In real-time applications based on hand gestures, the main challenge is to detect the hand(s). In this paper, we present and analyze existing approaches for real-time hand detection. Then,...
To translate the gesture performed by the user in a video sequence into meaningful symbols/commands, feature extraction is the first and most crucial step in such systems which measures the detected hand positions and its movement track. We propose an efficient approach based on inter-frame difference (IDF) to handle the hand movement tracking, which is shown to be more robust in the accuracy aspect...
Robust detection of skin color is a difficult task since color information changes under different lighting conditions. Previous research indicated that human skin color is restricted to a small range of values in certain color coordinate systems. However, the ranges tend to shift with varying illumination according to our experiments. It is therefore unattainable to derive a universal standard for...
