Problem with implementing RLC function...

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

Hi

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]

   a=diff(img,1,2)
   n=nnz(a)

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]

Rows=diff(img,1,2)
Columns=diff(img,1,1)

n=nnz(Rows)+nnz(Columns)
