removesigroi

Remove signal regions of interest

Since R2020b

Syntax

roilimsout = removesigroi(roilims,s)

Description

roilimsout = removesigroi(roilims,s) removes signal regions of interest specified in roilims that have a length of s samples or less.

Examples

Remove Regions of Interest

Create a two-column matrix of integers that can represent regions of interest of a signal. Remove any regions that are six samples in length or shorter.

rois = [1 6; 17 26; 24 32; 36 40];

xrois = removesigroi(rois,6)

xrois = 2×2

    17    26
    24    32

Input Arguments

roilims — Region-of-interest limits

two-column matrix of positive integers

Region-of-interest limits, specified as a two-column matrix of positive integers. The ith row of roilims contains nondecreasing indices corresponding to the beginning and end samples of the ith region of interest of a signal.

Example: [5 8; 12 20; 18 25] specifies a two-column region-of-interest matrix with three regions.

Data Types: single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64

s — Maximum length of regions of interest to remove

nonnegative integer

Maximum length of regions of interest to remove, specified as a nonnegative integer.

Data Types: single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64

Output Arguments

roilimsout — Modified region-of-interest limits

two-column matrix of positive integers

Modified region-of-interest limits, returned as a two-column matrix of positive integers. Output limits are returned in sorted order using the sortrows function.
