ABSTRACT
ABSTRACT
The main purpose of digital image enhancement processing is to improvethe visual
sense quality of the image, such as removing of noise in the image, changing the
brightness, color, enhancing some ingredients in the image, inhibiting some of the
ingredients, and performing the geometric transformation in the image, so we can
improve 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 it
can not be avoided. In education of image enhancement processing, Matlab image
processing toolbox has been favored by many educators. However, when users enter the
image processing functions and statements in the MATLAB command window, the
demo windows will appear everywhere, this causes some difficulties in visual
comparison. What’s more, when the users adjust the parameters, they have to re-enter
the relevant code completely, therefore, the demonstration process becomes tedious, the
whole process seemed scattered and messy.
In order to solve the above problem, we designed more reasonable User Graphical
Interface by using MATLAB GUI, and this interface allows teachers and students to use
the interface components, such as menus, buttons, input boxes and sliders, so they can
control the input parameters and make choices of the specific image processing
technology. Therefore, the teaching of teachers and the learning of students will become
concrete and intuitive.
This thesis introduce a method using MATLAB to develop a teaching
demonstration system of image enhancement processing. First, we discusses the work
principles in a variety of image enhancement processing technology. And then, we
discusses how to use MATLAB GUI to design a common teaching demonstration
system of image enhancement processing technology, we intuitively compares the
treatment results in the graphic interface, this is very convenient for the learner to
comprehensively grasp the entire image enhancement processing technology, so it
becomes easy to interactively demonstrate various image enhancement technologies and
their effects, therefore the abstract contents become concrete.
