trying to write a code on Image processing

I am a beginner in Image Processing using MatLab and I am trying to write a code which compares and detects the error between two images and marks the particular error portion and I am using Matlab 2011b., kindly help me

Answer 1

[Meshooo]

What do you mean by error?

[Mrutyunjay]

error means the difference in two images

Answer 2

[Koteswar Rao Jerripothula]

logical(abs(I1-I2))

[Mrutyunjay]

This is my code

close all a1=imread('master_image.png'); a=im2bw(a1); figure, imshow(a) b1=imread('test_image.png'); b=im2bw(b1); figure, imshow(b) k= imabsdiff(a,b); figure, imshow(k)

Im trying to find the difference in two images and the function 'logical(abs(a-b))' isn't working
