Hi every body. There is a binary image in a variable like :

img =
   1     0     0     0     1     0
   1     1     0     0     1     1
   1     0     1     0     1     0
   0     0     0     0     1     1

I need to return count changed binaries from 1 to 0 and unlike, for each row.

For example :

in each rows of 'img' variable result of counting changed binaries must be :

First row = 3
Second row = 2
Third row = 6
Fourth row = 1

At last that function must return (3 + 2 + 6 + 1) = 12

I don't know how do that !

Please help me. Tnx
