GUIDE-Matlab’s GUI

GUIDE stores GUIs in two files:
– .fig file – Contains a complete description of the GUI figure layout and the GUI components
• Changes to this file are made in the Layout Editor

– .m file – Contains the code that controls the GUI
• Initialization code and callbacks
• You can program the behavior of the GUI in this file using the M-file Editor

• Many of the interactive tools of the Image Processing Toolbox are modular and can be combined into your
custom GUI

– For image processing applications

  • imcontrast,
  • imcolormaptool,
  • imcrop,
  • imdisplayrange,
  • imdistline,
  • imageinfo,
  • immagbox,
  • imoverview,
  • impixelinfo,
  • impixelregion,
  • impixelregionpanel,
  • imsave,
  • imscrollpane

Open a file in the directory:

[filename,pathname]= uigetfile({'*.jpg';'*.bmp';'*.tif';'*.png'},'Choose a file');
str=[pathname filename];
im=imread(str);

or

[a b]=xlsread(str);
