NSEGMENT
NAME
nsegment - segment coefficient data into N stationary regions
SYNOPSIS
nsegment
(-i item) (-n numseg) (-c) file
DESCRIPTION
nsegment
uses a dynamic programming procedure to determine the location of N-1 boundaries
in time of a coefficient item, such that if each region was replaced by its mean,
the squared distortion error would be at a minimum. The algorithm is taken from
Bridle & Sedgwick, ICASSP 1977.
Options
and their meanings are:
-I
Identify program and version.
-i item
Select input item numbers.
-n numseg
Specify the number of segments to divide the item into. Default 2.
-c
Output the result as a coefficient item. Default output an annotation item.
INPUT ITEMS
11.xx
Any coefficient data.
OUTPUT ITEMS
AN
N-1 boundary locations.
CO
(optional) reconstructed segmented mean spectra.
