matlab image subtraction

hi,
I am doing project in digital radiography. As part of my project i need matlab code for image subrtraction with different weighted factor.

 

[Robinenemy]

matlab program for image subtraction

There is a direct command in matlab for images subtraction i.e.

I = imread('rice.tif');
Iq = imsubtract(I,50);
subplot(1,2,1), imshow(I)
subplot(1,2,2), imshow(Iq)
You can use any weighing factor with that.


Regards

Robin
