SAGA.imagery_segmentation.2: Seed Generation

The tool allows one to create seed points from a stack of input features. Such seed points can be used, for example, as input in the 'Seeded Region Growing' tool.<br/><br/>

Please set a value for FEATURES.

Seed Type

string

Method

string

Bandwidth (Cells)

number

Standardize the input features, i.e. rescale the input data (features) such that the mean equals 0 and the standard deviation equals 1. This is helpful when the input features have different scales, units or outliers.

boolean

Weighting Function

string

Inverse Distance Weighting Power

number

Calculates weights for distance plus one, avoiding division by zero for zero distances

boolean

Gaussian and Exponential Weighting Bandwidth

number

Outputs
