new to image processing and will like to get some guides for this question. Add sine wave noise to the image and then remove it by band-reject filtering and notch filtering.

Add sine waves to the face using the following commands. Then remove the noise using band-reject fltering or notch fltering.
[x,y]=meshgrid(1:256,1:256);
s=1+sin(x+y/1.5);
ep=(double(en)/128+s)/4;

That's pretty much what my attached demo does. Adapt it as needed.

Replace
imshow(grayImage , [9 9])
with
imshow(grayImage , [])
also, there is no label() function. Maybe you meant xlabel() or bwlabel().
