Computes the Sum of Absolute Difference (SAD) for the given two blocks
.
\[ SAD = \sum_{i=0}^{n-1}\sum_{j=0}^{n-1} |Cur_{ij}-Ref_{ij}| \]
currentImg | : img for which we are finding the SAD |
refImg | : img which the SAD is being computed |
offset_curr | : offset applied to img current |
offset_ref | : offset applied to ref img |
mbSize | : the side of the 2 square blcks |
w | : width of images |
