Mouse Movement through Finger by Image Grabbing

Touch less Interactive screen or system is an upcoming technology in the real life world, which will be another biggest realization followed by the technologies based on the monitors cove as PC monitor, TV Screens without a stroke or touch. The aim of this project is to develop a touch less interactive screen which helps to ease the controlling of any kind of monitors. Project is based on MATLAB platform. In this work, the finger gestures which are captured by a webcam and that will be converted into mouse movements to control the screen. Various Analysis result has included in the report to show the feasibility of the application of this development. A Graphical Interface User (GUI) is developed to let the user to choose perform calibration and number of times it’s required to perform calibration and to trigger the program upon user’s request.

A Method of Measuring Laser Divergency Angle by Focus Spot Method Based on Comparative Measurement

his paper is based on image processing techniques, combined principle of Matrix CCD and image grabbing card , measured divergency angle of laser by focus spot method. In windows environment, using VC++ develop tools, achieved De-nosing and recognition of image and the measuring of laser divergency angle. A standard laser which of divergency angle is known is measured with focus spot proposed by the paper, the relative error ≦ 5%，which meets demand of test precision.

The Redevelopment of Matrox Meteor-II/Digital Image Grabbing Board with VC++

In order to store real-time images, a digital image grabbing system is proposed in this paper. The principles and design of real-time image continuous grabbing, displaying and storing system are presented. It has been redeveloped based on Matrox Meteor-II /Digital Image Grabbing Board by the use of VC++, and the whole implementation was introduced by an example. The developed image capture software is given at the end of this paper. And this gives a new thought and platform for real-time image processing.
