eigenFeature

Object for storing eigenvalue-based features

Since R2021a

Description

The eigenFeature object stores an eigenvalue-based feature vector extracted from point cloud data.

Creation

Syntax

features = eigenFeature(featureVector,centroid)

Description

features = eigenFeature(featureVector,centroid) constructs an eigenFeature object from the feature vector featureVector and the centroid centroid. The featureVector argument sets the Feature property, and the centroid argument sets the Centroid property.

Properties

Feature — Feature vector

seven-element vector

Feature vector, specified as a seven-element vector of the form [linearity planarity scattering,omnivariance anisotropy eigenentropy change in curvature].

Centroid — Centroid

three-element vector

Centroid, specified as a three-element vector in the form [x y z].

Examples

Create eigenFeature Object

Create a feature vector and set the centroid for the eigenFeature object.

featureVector = rand(1,7);
centroid = rand(1,3);

Create an eigenFeature object.

eFeature = eigenFeature(featureVector,centroid)

eFeature = 
  eigenFeature with properties:

     Feature: [0.8147 0.9058 0.1270 0.9134 0.6324 0.0975 0.2785]
    Centroid: [0.5469 0.9575 0.9649]
