Matlab Code For Identification Of Graphics Objects In Aircraft Displays

Abstract

This paper is aimed at understanding, utilizing and improving the existing system and automating the graphics testing process. The paper involves developing an automation design for automating the graphics testing process involved in software testing of aircraft displays. The paper comes under software development; there are so many steps in software development like Requirement analysis, Design, Implementation, Testing and evolution. So testing is the one of the step which comes under software development. We are designing an automation tool in graphics testing. Graphic testing tests the display devices. The main motivation of this project is to save the time because current approach involves user to read each and every message box which gets popped up while executing script. This approach involves a lot of manual effort and a person has to physically present and do the test execution and also there is possibility of mistakes when a non-trained person working on it. So to make initial test set up as fast as possible, with no errors and with no manual effort we are developing an automation tool. The tool includes techniques of image comparison, optical character recognition and template matching. Our automation should be able to handle all kinds of text and digits. Implementing a design which is able to recognize characters which pops up from window and takes a decision of pass/fail based on the recognized characters, while doing testing automatically, for that we use optical character recognition and template matching is mainly used for object recognition. Image comparison is used to capture an image and do the executions process automatically.
