e gaussian and periodic noise this is my code for them and they didnt work how can i fix them plz?
this is the gaussina noise code
a=(app.Image);
noise=imnoise(a,'gaussian');
I=imshow(noise,'parent',app.UIAxes2,...
'XData',[1 app.UIAxes2.Position(3)],...
'YData',[1 app.UIAxes2.Position(4)]);
app.UIAxes2.XLim=[0 I.XData(2)];
app.UIAxes2.YLim=[0 I.YData(2)];
and this the periodic noise code
a=(app.Image);
s=size(a);
[x,y]=meshgrid(1:s(1),1:s(2));
p=sin(x/3+y/5)+1;
noise=(im2double(a)+p/2)/2;
I=imshow(noise,'parent',app.UIAxes2,...
'XData',[1 app.UIAxes2.Position(3)],...
'YData',[1 app.UIAxes2.Position(4)]);
app.UIAxes2.XLim=[0 I.XData(2)];
app.UIAxes2.YLim=[0 I.YData(2)];
i also have this low pass filter also doesnt work how can i fix it
a=(app.Image);
f1=fspecial('average',[5,5]);
I=imshow(f1,'parent',app.UIAxes2,...
'XData',[1 app.UIAxes2.Position(3)],...
'YData',[1 app.UIAxes2.Position(4)]);
app.UIAxes2.XLim=[0 I.XData(2)];
app.UIAxes2.YLim=[0 I.YData(2

Not sure what that means. Does it now work, or not? Since you accepted my suggested fix, I assume it's all working now. If not, attach your .mlapp file with the paperclip icon.

Instead of
f1=fspecial('average',[5,5]);
I=imshow(f1,'parent',app.UIAxes2,...
'XData',[1 app.UIAxes2.Position(3)],...
'YData',[1 app.UIAxes2.Position(4)]);
app.UIAxes2.XLim=[0 I.XData(2)];
app.UIAxes2.YLim=[0 I.YData(2
try
f1=fspecial('average',[5,5]);
imshow(f1, [], 'parent',app.UIAxes2)
axis('on', 'image')
@jana you've asked 15 questions but have never awarded any of the people who helped you with "reputation points" by clicking the "Accept this answer" link. They'd appreciate it if you did that. 🙂

You had a number of major errors in those functions. I fixed them.
