Create a Point Pattern on a Simulated Tissue Image

This function generates a spatial point pattern with different types of points (A, B, C) distributed over the simulated tissue structure.

Usage

createPointPatternTissue(tissueImage, intA, intB, intCInA, intCInB)

Arguments

tissueImage

Matrix; A binary matrix representing the simulated tissue.

intA

Numeric; Intensity of type "A" points (points per unit area) on tissue regions.

intB

Numeric; Intensity of type "B" points (points per unit area) on non-tissue regions.

intCInA

Numeric; Intensity of type "C" points placed in extended regions around tissue.

intCInB

Numeric; Intensity of type "C" points placed within tissue.

Value

A ppp object representing the spatial point pattern.

Examples

tissueImage <- simulateTissueBlobs(128, 100, 7)
createPointPatternTissue(tissueImage, 0.1, 0.1, 0.005, 0.005)
#> Marked planar point pattern: 1873 points
#> marks are of storage type  ‘character’
#> window: rectangle = [0, 128] x [0, 128] units
