In Chamodi88/ImageSegmentation: New package for image segmentation

Description

Documentation for the extract method of single cluster/class from segmented images

Usage

extract(segimg, ..., cluster = NULL, org_image = NULL, b = NULL)

## S3 method for class 'Table'
extract(segimg, cluster = 1, org_image = NULL,
  b = NULL, ...)

## S3 method for class 'THsegments'
extract(segimg, ..., cluster = 1)

Arguments

segimg	an object of class Table or THsegments or grayimage
...	graphical parameters to imageplot
cluster	cluster number to be extracted
org_image	original image to be segmented
b	number of bands in the original image

Examples

## Not run: 
library(stars)
tif <- read_stars(system.file("extdata/image.tif", package="ImageSegmentation"))
p <- seg_kmeans(tif,3,5)
extract(p,2,tif,3)

e <- RGBtoGRAY(tif)
s <- segmentation_threshold(e)
extract(s, cluster=3)
