摘要：The aim of this paper is to provide with a real time application based on hand gesture recognition. Virtualtouch is a concept whereby any normal surface with no internal circuitry and hardware for touch sensitivity, is convertedinto a touch sensitive surface by using image processing techniques.Using such a technique the paper presents thetransformation of a plain white wall into a large touch wall. The virtual touch wall aims at building a gesture sensitiveenvironment for users, to provide them new ways of interaction in their work atmosphere and in their recreational space.The hardware requirements of the system are kept on the minimum , limiting only to a simple USB webcam and a PC.Other alternatives to the PC have also been presented , such as the Beagle Board , which is a mini version of a PC and veryinexpensive .The approach is based on simple and fast motion detection trying to eliminate unnecessary regions of interestand a recognition algorithm based on the hand contours , their convexities and a further comparison of hand shapes basedon HU moment matching which works on image contours .The paper also presents a way of improving the distorted handcontours by distinguishing between external contours and holes and explicitly filling up holes .The use of a predefined setof contours for each gesture helps in better recognition .A simple state machine is implemented to further improvereliability .A total of 5 gestures have been implemented and tested on the PC and the Beagle Board and the performancecompared. The Linux XLIB library and the X display functions have been utilized to control mouse cursor actions andother display properties of the wall.
