Is it intended to use edgediff instead of ssim_map when scale is 0?

[futur63]

if (scale == 0) {
...
for(int twice=0; twice < 2; twice++) {
if (twice) { ssim_map = edgediff; }
...
}
}

// worst ssim in a particular 4x4 block (larger blocks are considered too because of multi-scale)
resize(ssim_map, ssim_map, Size(), 0.25, 0.25, INTER_AREA);

You're right. This wasn't the intention.

Is there any suggestion how to fix this?
