In your code pushbutton4_Callback, you have two variables, image1 and image2. One of those two is an array of uint8 and the other of them is an array of double. In order to use bitxor, you have to convert the array of double into an array of uint8. For example, possibly

bitxor(image1, uint8(image2))

this error

[Walter Roberson]

bitor(image1(i-1,j), bitor(image1(i,j-1), bitor(image1(i+1,j), image1(i,j+1))))

In future please copy error messages as text (possibly in addition to images) so that people can copy your code instead of having to type it in by hand.

ok sorry for that.

in pdf

f(i,j) = g(i−1,j)CORg(i,j−1)CORg(i,j)CORg(i+1,j)CORg(i,j+1)

maybe wrong in syntax.. it is correct?

bitor(image1(i-1,j), bitor(image1(i,j-1), bitor(image1(i+1,j), image1(i,j+1))))

[Walter Roberson]

I do not recognize what COR is intended to mean. The code might be right, if COR stands for bitwise-OR . If COR is intended to mean XOR then

bitoxr(image1(i-1,j), bitxor(image1(i,j-1), bitxor(image1(i+1,j), image1(i,j+1))))
