Abstract: The aim of image processing is to help the computer to understand the content of an image. OpenCV is a library of programming functions mainly used for image processing. It provides de-facto standard API for computer vision applications. We can solve many real time problems using image processing applications. In this paper, sample real time image processing applications of OpenCV are discussed along with steps.

An additional web-camera extension can also be used, for multiple usage such as to operate and record the operation. A inverted mask has been created to save the content written in air as .PNG file using screenshot.
In Gesture Based Visual Writing System, we have implemented gesture controlled real time application [ex: .ppt] , including various gestures to operate namely thumb finger open for previous slide, little finger open for forward slide, fore finger open to write/doodle, fore-middle-ring fingers open to erase doodle, thumb and little finger open for screenshot , thumb-fore-little fingers open for pseudo screen.
