Answer 1

Instead of handling data as an array of bytes, you can handle it as an array of integers.

int* p = (int*)((byte*)scan0.ToPointer() + y * stride);
int* p2 = (int*)((byte*)scan02.ToPointer() + y * stride2);

for (int x = 0; x < nWidth; x++)
{
    //always get the complete pixel when differences are found
    if (*p2 != 0)
      *p = *p2

    ++p;
    ++p2;
}
