Object for storing eigenvalue-based features
eigenFeature object stores an eigenvalue-based feature
vector extracted from point cloud data.
features = eigenFeature(
eigenFeature object from the feature vector
featureVector and the centroid
argument sets the
Feature property, and the
centroid argument sets the
Feature — Feature vector
Feature vector, specified as a seven-element vector of the form [linearity planarity scattering,omnivariance anisotropy eigenentropy change in curvature].
Centroid — Centroid
Centroid, specified as a three-element vector in the form [x y z].
Create a feature vector and set the centroid for the
featureVector = rand(1,7); centroid = rand(1,3);
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]
