i have a err1.m program ,as follows
y=imread('c:/5.png');
gg=rgb2gray(y);
r=0;
f=5;
news=25;
b=20;
for i=6:894
for j=6:1594
vp=gg(i,j);
q=mean2(gg(i-5:i+5,j-5:j+5));
s=std2(gg(i-5:i+5,j-5:j+5));
zp = (vp-q)/s;
if(s<news),
if(s<f),
r = (news*(s/f));
else
r = 50;
end
end
nmean= b+(q-0)*((255-30)-(0+30))/(255-0);
np(i,j)= nmean + zp*r;
if(np(i,j)<=0)
newvp=0;
elseif(np(i,j)>=255)
newvp=255;
else
np(i,j)=np(i,j);
end
disp('Exec');
j;
end
end
imshow(np)
where i read an input image , apply some algorithm over it and print the resultant image . My objective is to create a GUI for this program , i called the .m file using push button callback , i used this code
% --- Executes on button press in Execute. function Execute_Callback(hObject, eventdata, handles) % hObject handle to Execute (see GCBO) % eventdata reserved - to be defined in a future version of MATLAB % handles structure with handles and user data (see GUIDATA)
err1
to run the file and i got no output and the process does not seem to end, the err1.m program works fine on its own , but i get no results when i call the .m file inside a push button callback. I'm just a beginner in using matlab . please help me find a solution.
