# reducepoly

Reduce density of points in ROI using Ramer–Douglas–Peucker algorithm

*Since R2019b*

## Description

## Examples

## Input Arguments

## Output Arguments

## Algorithms

The Ramer-Douglas-Peucker line simplification algorithm recursively subdivides a shape
looking to replace a run of points with a straight line. The algorithm checks that no point in
the run deviates from the straight line by more than the value specified by
`tolerance`

.
