Hi Jana,

I had a look into your code. Can you give some clarity on which functionalities in your app is not working. It can help me have a better understanding of the issue

Glad

Hello Jana,

 a=(app.Image);
 f1=fspecial('average',[5,5]);
 
 % N-D filtering of multidimensional images
 i2=imfilter(a,f1)
 
 I=imshow(i2,'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)];
