simRasterSegments2: Simulate raster segments (faster version)

In joaofgoncalves/SegOptim: Optimization of Image Segmentation Parameters for Object-Based Image Analysis (OBIA)

Simulate raster segments (faster version)

Description

Uses simulated data for n classes, performs modal smoothing and then checks for raster clumps similar to segments

Usage

simRasterSegments2(
  nr = 100,
  nc = 100,
  nClasses = 10,
  winSize = 3,
  directions = 8
)

Arguments

nr	Number of rows for the simulated SpatRaster (default: 100).
nc	Number of columns for the simulated SpatRaster (default: 100).
nClasses	Number of classes to simulate (default: 4). Larger numbers will tend to generate more segments.
winSize	Window size for performing the focal operation using the modal function (higher values will generate less segments; default: 3)
directions	integer indicating which cells are considered adjacent. Should be 8 (Queen's case) or 4 (Rook's case)

Value

A simulated SpatRaster with segments.
