how can i call parameter from one menu to another menu in GUI?

Dears,

i need your help... i had designed gui interface composed of five menues. first menu include filters and i need to apply histogram function on filtered image from second menu and the same for other menues.

i need only to know how to call filter method in histogram menu and same for edge and sharpen filters.

i had attached the printscreen of gui interface.

any one have an idea.

with many thanks.

Put the important code into a function. Call the function in multiple places.

For example, if button A needs to trigger the action of button B, then put the real work of button B into buttonB_worker and have buttonB_Callback and buttonA_Callback both call buttonB_worker.

i tried to call using handle but doesn't work with me.

Please see my filter code.

function WMF_Callback(hObject, eventdata, handles)

v = get(handles.text5,'string'); 

m = 'Weighted Median Filtering';
set(handles.text5,'string',m);

I = handles.I;

axes(handles.axes4);
handles.I = I;
imhist(I);

c = get(handles.popupmenu2, 'value');

if (c == 1)
h = 1/100;
elseif (c == 2)
h = 2/100; 
elseif (c == 3)
h = 3/100;
elseif (c == 4)
h = 4/100;
elseif (c == 5)
h = 5/100; 
elseif (c == 6)
h = 6/100; 
elseif (c == 7)
h = 7/100;
elseif (c == 8)
h = 8/100; 
else (c == 9)
h = 9/100; 
end

n = get(handles.popupmenu1, 'value');

if (n == 1)
p = 'salt & pepper';
elseif (n == 2)
p = 'speckle'; 
else (n == 3)
p = 'gaussian';
end

BW1=imnoise(I,p,h);
axes(handles.axes2);
handles.BW1=BW1;
imshow(BW1);
%histgrom
axes(handles.axes5);
handles.BW1=BW1;
imhist(BW1);

a = BW1;
b = a;
W= [10, 7, 6; 6, 10, 6; 6, 6, 6]/9;
[row col] = size(a);
MA=cputime;
for x = 2:1:row-1
    for y = 2:1:col-1
%%To make a 3x3 weighted mask into a 1x9 mask
a1 = [W(1)*a(x-1,y-1) W(2)*a(x-1,y) W(3)*a(x-1,y+1) ...
      W(4)*a(x,y-1) W(5)*a(x,y) W(6)*a(x,y+1)...
      W(7)*a(x+1,y-1) W(8)*a(x+1,y) W(9)*a(x+1,y+1)];
a2 = sort(a1);
med = a2(5); % the 5th value is the weighted median

b(x,y) = med;
    end
end

DA=cputime-MA;
handles.DA=DA;
set(handles.edit2,'String',DA);

de=b-I;
%%%%MSE
Er_WMF=sum(sum(de.^2))/ [row*col]
set(handles.edit1,'string',Er_WMF);
%%%%PSNR
psnr = 10*log10(255*255/Er_WMF); 
set(handles.edit3,'string',psnr);

axes(handles.axes3);
handles.b=b;
imshow(b);
title('Filtered Image');

axes(handles.axes6);
handles.b=b;
imhist(b);

i need to call imhist function from another menu.so, how can i dot it.

for example, after loading the image and apply the filter from the menu and need to select the type of histogram from another menu.

Thank you in advance
