Hi everybody, hi have an RGB image and i want to remove all pixels which were equal to 1 from the following command:
FIND=(A(:,:,1)>=175 & (A(:,:,1)<=193));
with A that is the 4000x6000x3 uint8 image.

YOu cannot remove them, replace them with any other value.......
A = I(:,:,1) ;
idx = A>=175 & A<=193;
A(idx) = 0 ;
I(:,:,1) = A ;

okay, but i just want to select (A(:,:,1)>=175 & (A(:,:,1)<=193)) and not (A(:,:,i)>=175 & (A(:,:,i)<=193))
