imnoise

"imnoise expects pixel values of data type double and single to be in the range [0, 1]. You can use the rescale function to adjust pixel values to the expected range. If your image is type double or single with values outside the range [0,1], then imnoise clips input pixel values to the range [0, 1] before adding noise."

So you should im2double() your uint8.

so here is the code line how should i rewrite this

app.TempEffect=imnoise(app.Modified,'guassian',app.Noise);

I don't see how this is an issue of input class or scale. Both imnoise() and imadjust() support uint8 inputs. Both will blindly process floating point images regardless of scale (not that the outputs will be useful in those cases).

A = imread('cameraman.tif'); % this is uint8
Ad = double(A); % this is improper uint8-scale double

B = imnoise(A,'gaussian'); % returns no error with uint8
Bd = imnoise(Ad,'gaussian'); % returns no error with improperly-scaled double

C = imadjust(A,[0.1 0.9]); % returns no error with uint8
Cd = imadjust(Ad,[0.1 0.9]); % returns no error with improperly-scaled double

If the sigma parameter (app.Noise) were uint8 class, that's not the error message you would get. Similarly, If the range parameters for imadjust were uint8 class, you would either get no error or an error which differs from the one shown.

If you're getting an error, it's either because those functions don't exist, they don't exist on the path, or because something is shadowing them.

Do you have Image Processing Toolbox?

What do you get when you check the path for those functions:

which imnoise -all

[Walter Roberson]

Ah, I see now that the wording could mean that IF your values are floating point then that range is expected, rather than saying that only floating point is expected.

[DGM]

I could understand that someone might accidentally have a file that's shadowing one function, but both being shadowed seems like a stretch.

I suspect that the app may be something that was downloaded without knowing its dependencies, but I can't know that. If it turns out that OP doesn't have IPT, then MIMT imadjustFB() and imnoiseFB() should be drop-in replacements for the usage that's shown.
