Fault management is used to detect, isolate, and repair problems in communication networks. Alarms are considered an external manifestation of faults occurring inside the managed network. These faults may affect the network’s hardware and sof

Normalized Cross Correlation (NCC) algorithm is robust, but it has poor real-time performance due to its large amount of computation.

It s a tool to compute the w-correlation between two timeseries

ZNCC Normalized cross correlation m = zncc(w1, w2) Compute the zero-mean normalized cross-correlation between the two equally sized image patches w1 and w2. Result is in the range -1 to 1, with 1 indicating identical pixel patterns.-ZN
