how to store intensity values of an image into a matrix via matlab code.i have tried a code which prints the values of intensities using:
for i=1:1.0:455
for j=1:1.0:306
val=impixel(img2,i,j);
disp(val);
end
end
**Image array is already the intensity matrix..but how can i store it into an array which is user defined variable
