rmslivers

Remove polyshape boundary outliers

collapse all in page

Syntax

polyout = rmslivers(polyin,tol)

Description

example

polyout = rmslivers(polyin,tol) returns a polyshape object made up of the boundaries of polyin with any outlier vertices removed. tol defines boundary outliers based on the ratio of relative distances between vertices.

Examples

Open Live Script

Remove an outlier boundary point from a polygon, eliminating the extraneous sliver or antenna effect.

polyin = polyshape([0 0 2 2 1.0001 1 0.9999],[2 0 0 2 2 10 2]);
plot(polyin)
xlim([-0.5 2.5])
ylim([-2 12])

polyout = rmslivers(polyin,0.001);
plot(polyout)
xlim([-0.5 2.5])
ylim([-2 12])

Input Arguments

collapse all

Input polyshape, specified as a scalar, vector, matrix, or multidimensional array.

Data Types: polyshape

Outlier tolerance, specified as a scalar. When the input polyshape is an array, rmslivers removes outliers from each element of the array according to tol.

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

Outlier Tolerance

The outlier tolerance specifies the allowable ratio between the relative distances of vertices in a polygon region. For example, in the following figure, if ab≤tol for a specified tolerance tol, then rmslivers does not remove the vertex v. If ab>tol, then rmslivers removes v, eliminating the sliver.
