Gesture recognition and finger tip detection for human computer interaction

The paper proposes a novel gesture recognition and finger tip detection algorithm for Human Computer Interaction, in particular mouse control operations using real time camera. The hand gestures are captured using real time camera. First, the hand region alone is segmented using region growing algorithm followed by morphological operations. The centroid of the palm region is calculated and the finger tips are then detected using the convex hull algorithm. The proposed method is tested on five different gestures and the results prove that the gestures are able to be recognized and the finger tips detected. The method can be applied for hand gesture controlled mouse operations.
