Erosion: Morphological Erosion

In rwang14/implant: A High-throughput Phenotyping Pipeline for Image Processing and Functional Growth Curve Analysis

Description

This function is used to perform morphological erosion of an image.

Usage

erosion(imagefile, mask = matrix(1, 3, 3))

Arguments

imagefile	a binary matrix of the segmented image.
mask	a matrix constructed by structuring elements.

Value

a binary matrix of the eroded image.

Examples

#read an RGB image
library(png)
image = readPNG(system.file("extdata", "image1.png",
                             package = "implant",
                             mustWork = TRUE))[ , ,c(1:3)]

imageB = imageBinary(image, weight = c(-1, 2, -1),
                     threshold1 = 30 / 255,
                     threshold2 = 0.075)

imageBE = erosion(imageB, mask = matrix(1, 5, 5))
