i have to compare two S2 products on the same area taken at different times.
So my idea was to first standardize the values in each band. Exactly if i can assume brightness = mean and contrast = stddev i was thinking to apply the classic standardization formula:
B_standard = (B_x - mean (B_x)) / stddev (B_x).
First of all i wonder if this is a correct procedure and if so i can’t find a way to obtain it in SNAP.
Band-math can’t be used on whole bands at once and even if i want to do it on each band one by one the functions mean and stddev don’t calculate it on the whole band’s value in a single run.
Is there a way in SNAP to obtain such results?
If not can you help me with any different idea about how to get similar standard values?
