The otsuThreshold function was creating an empty Array for the sigmas variable and this sometimes failed because the last value was not always written to. This commit adjusts the size of the sigmas array to better match the values that are assigned to it
Prior to this change, edge tracking CPU backend kernel wasn't processing the batch input sets. Thus, the output of corresponding input sets was missing in the array returned by canny API. This is fixed now. Added a batch test for this scenario.

PR adjusts the size of the array so that the extra element is not used.
Description
The otsuThreshold function was creating an empty Array for the sigmas variable
and this sometimes failed because the last value was not always written to. This
PR adjusts the size of the array so that the extra element is not used.
This PR also removes a couple of reductions in the otsuThreshold function. These
reductions are replaced by a scan.
