fnorm

$ \bigcirc$Name


fnorm Compute the norm of a Fimage




$ \bigcirc$Command Synopsis


fnorm [-p p] [-s] [-v] [-b b] [-c ref] [-n] [-t t] in .



-p p : compute average L $ \hat{{}}$  p norm

-s : compute L $ \hat{{}}$  infinity norm (sup of absolute values)

-v : compute average total variation

-b b : number of lines to crop on the borders (default: 0)

-c ref : compare with Fimage ref (ie compute |   |  in - ref |   |  )

-n : normalized comparison (with -c), ie |   |  in - ref |   |  / |   |  ref |   |  )

-t t : force result to 0 if less or equal than threshold t

in : input Fimage

. (screen output) : computed norm
