MATLAB: Background for design gui

guiimage processing

How do I use background for gui design?

In the OpeningFcn callback of your GUI add below code

BkImage = importdata('backgnd.jpg'); %Read the image file
axes(handles.BkAxes);
image(BkImage);

You could just blur the heck out of it with conv2(). Or else use the image to model a perfectly smooth function, like a quadratic or something. I used polyfitn for this but John removed it from the File Exchange. Maybe you could try this instead: http://www.mathworks.com/matlabcentral/fileexchange/13719-2d-weighted-polynomial-fitting-and-evaluation

push buttton callback:

set(handles.togglebutton1,'value',0);
set(handles.togglebutton2,'value',0);
