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')

thank u so much genuienly i cant thank you enough truly last thing though these codes for turning the grayiage to blue and green whats the problem with them a=(app.Image);
green=a;
green(:,:,3)=0
setappdata(0,'filename',green);
setappdata(0,'imrotation',green);
I=imshow(green,'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)];
the blue code
a=(app.Image);
blue=a;
blue(:,:,2)=0
setappdata(0,'filename',blue);
setappdata(0,'imrotation',blue);
I=imshow(blue,'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)];
