Hi every body. There is a binary image in a variable like :
img =
1 1 0 0 0 1 0
1 1 1 0 0 1 1
0 1 0 1 0 1 0
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
