Basic image tools matlab1/6/2024 ![]() Programming the push button (LOAD IMAGE):įor loading the image to our design once we press the pushbutton, we should edit the pushbutton1 callback. Str= get(hObject,'String') % file location entered in this text box will be assigned to a variable named ‘str’. Add a line to the call back function to access the file location entered in the edit text box. Programming the edit text box (TYPE IMAGE LOCATION HERE):Įdit text box contains a call back function. Usually a callback function needs at least 3 input arguments (handles, event data, hobject). By writing an appropriate callback functions we can make the components to respond to user interactions. Callback functions controls the component behavior. While saving the GUI layout, it will automatically create an callback function corresponding to each components which we added in our design. We can also open the editor window from View> Editor on the figure window. A ‘.m’ file will be opened in default editor window of MATLAB. ‘.m file ‘contains the code which controls our GUI. Once you save GUI, as mentioned earlier two files will be created with ‘.fig’ and ‘.m’ extension. Click on the save button on the figure window. In the same way add items to list box in the panel window.Īt last, final layout will be as shown in the figure: Now edit the given string with different types of noise like salt and pepper, speckle. Right click on the pop up menu and click on the button near to ‘String’. Correct the text shown in each component. Edit the properties of each object in their corresponding property inspector.Īlthough we have added the components to the layout area the text shown in GUI window is not appropriate. Similarly add all the objects from the component palette to layout area as shown below. Properties associated with this text box such as background color, font size can be edited on its property inspector. Static text is a text box which never changes while using the GUI. First we need to have a title for our GUI. Image arithmetic operations are also included in this GUI using an Image Arithmetic panel window.ġ. Effect of different types of noise on the image can be analyzed using this GUI. Color space of the selected image can be varied by selecting any button (gray code or ycbcr) on the button group provided. Once if you enter the file location of the image to be loaded and click on the LOAD IMAGE push button, selected image will be loaded on the ‘Axes ‘ box on the grid. This tutorial helps you to perform image processing on image selected. Let’s create a simple image processing tool box using GUI. Several other features such as font color, font size, background color can be applied to the components added by making corresponding changes in the property inspector window. Input your title name at the ‘String’ option in the property inspector window. To edit the properties of the components, right click on the component and select “Property Inspector”.įor example to add a title to your GUI, drag static text box to the lay out area and right click on the text box. ![]() Add components : Simply drag and drop items from the component pallete to layout area to create your GUI. Setting GUI window size: By dragging the resize box on the layout area we can set the GUI dimension as per our requirement.Ĥ. Select the type of GUI: For that, choose “Blank GUI (Default)” option in the ‘GUIDE Quick Start’ dialogue box. m file: it contains the code that is needed to control GUI behavior.ġ. fig file: it contains the layout of the GUI. We can edit the properties of each callback functions for making suitable response from the GUI as the user ineracts. ![]() Callback functions will be executed once an event occurs. Events may be click,double click,key press etc. Flow of the application is based on events. GUI interface is an event driven programming. Adding appropriate components we can create a GUI design for any application. ![]() MATLAB GUI contains several user interface tools like radio buttons,axes,check box,tables.sliders,list box,pannels.etc. Graphical user interface provides the user an interactive enviornment.Once the GUI is created the user need not know anything about the coding section. Using GUI we can perform any computations, communicate with any other UI’s, plot graps,create tables etc.
