Image Analysis from GUI with menu, listbox and pushbutton

Hello,

I would like to create a mainGUI which will have a menu bar and a listbox. I want to perform as follows: Step 1: Open Image from the menu 'Open Image' option. The listbox will show 'Image imported'.

Step 2: 'Median Filtering' from the menu: When 'Median Filter' is clicked, a subGUI for median filtering will pop up for filtering window options. Then I select my suitable filter size. Once 'Done' is clicked on the subGUI of the median filtering, the median filtering option will perform and then the listbox of the mainGUI will show the name of my process as 'Median Filter' with window size (that I selected from subGUI) displayed next to it.

A 'Delete' pushbutton on the bottom of the listbox to delete the 'median filter" if user wants to delete the median filtering. If I select'median filter' from the listbox and click 'Delete' pushbutton, then the median filtering step will be deleted and the image will go back to step 1.

Step 3: I also want to save all the steps that I performed as a text file so in future if I load that text file, I can run the steps that I perform previously. Also, I want to save a log file of all the steps including the values I have chosen.

Thanks in advance

Dear Image Analyst,

I checked the MAGIC gui but I do not see the required things I need. I specially need to display each step of my image processing on the listbox.

Let's say, When I load an Image, the axes1 will display the image and the listbox will show 'Image Loaded' Then I apply median filtering from menu. Then the listbox will show 'Median Filter'. The main thing I am interested is: When I select 'Median Filter' from the listbox and click 'Delete' pushbutton, the median filter step will be removed and the axes will display the loaded raw image.

Here is the gui that I am trying to make. I just don't understand how I can pass the string to the listbox and how the listbox can be interactive as I described.

function varargout = test_image_process(varargin)
% TEST_IMAGE_PROCESS MATLAB code for test_image_process.fig
%      TEST_IMAGE_PROCESS, by itself, creates a new TEST_IMAGE_PROCESS or raises the existing
%      singleton*.
%
%      H = TEST_IMAGE_PROCESS returns the handle to a new TEST_IMAGE_PROCESS or the handle to
%      the existing singleton*.
%
%      TEST_IMAGE_PROCESS('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in TEST_IMAGE_PROCESS.M with the given input arguments.
%
%      TEST_IMAGE_PROCESS('Property','Value',...) creates a new TEST_IMAGE_PROCESS or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before test_image_process_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to test_image_process_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".

Well not right out of the box it won't. You have to adapt it of course, but it will give you a good start.

I was able to add string of the process, however, the text is static, not interactive. For example, I want to delete median filtering from the listbox so I can delete this step from my analysis. The process will update automatically to the previous open image step and the axes will also show only open image step.

oldstr = get(handles.listbox1,'String') % The string as it is now. addstr = {oldstr,get(hObject, 'Label')} % The string to add to the stack. set(handles.listbox1,'String',addstr); % Put the new string on bottom.

[Image Analyst]

Why not make the choice of median filtering to be a checkbox?

[Muhammad Abir]

I want to build a work flow where I can add/delete each process. Deleteing each process will go back to previous step automatically
