when i run this

Code: Select all

identify -format '%[standard-deviation]' image.jpg
i get a value of
18232.1

but when i run

Code: Select all

identify -verbose image.jpg
i see in overall image statistics a standard deviation of 70.9422 (0.278205)

how can i get the value shown in the verbose output?

The first version converts the image to 16 bits/channel/pixel before the calculation.

You could:

Code: Select all

identify -format "%[fx:255*standard_deviation] (%[fx:standard_deviation])" x.jpg
