Design And Implementation Of Teaching Demonstration System Based On MATLAB In Image Enhancement

The main purpose of digital image enhancement processing is to improvethe visualsense quality of the image, such as removing of noise in the image, changing thebrightness, color, enhancing some ingredients in the image, inhibiting some of theingredients, and performing the geometric transformation in the image, so we canimprove the quality of the image or get unexpected visual artistic effect. Therefore,image enhancement has always been a long-term issue in research and education, and itcan not be avoided. In education of image enhancement processing, Matlab imageprocessing toolbox has been favored by many educators. However, when users enter theimage processing functions and statements in the MATLAB command window, thedemo windows will appear everywhere, this causes some difficulties in visualcomparison. What’s more, when the users adjust the parameters, they have to re-enterthe relevant code completely, therefore, the demonstration process becomes tedious, thewhole process seemed scattered and messy.In order to solve the above problem, we designed more reasonable User GraphicalInterface by using MATLAB GUI, and this interface allows teachers and students to usethe interface components, such as menus, buttons, input boxes and sliders, so they cancontrol the input parameters and make choices of the specific image processingtechnology. Therefore, the teaching of teachers and the learning of students will becomeconcrete and intuitive.This thesis introduce a method using MATLAB to develop a teachingdemonstration system of image enhancement processing. First, we discusses the workprinciples in a variety of image enhancement processing technology. And then, wediscusses how to use MATLAB GUI to design a common teaching demonstrationsystem of image enhancement processing technology, we intuitively compares thetreatment results in the graphic interface, this is very convenient for the learner tocomprehensively grasp the entire image enhancement processing technology, so itbecomes easy to interactively demonstrate various image enhancement technologies andtheir effects, therefore the abstract contents become concrete.
