In shannonlabumn/TubAR: Potato Tuber Trait Image Analysis

Measures the BB width, BB length, perimeter, convex perimeter, area, convex hull area, compactness, roundness, and maximum length values for each object in the image.

Description

Measures the BB width, BB length, perimeter, convex perimeter, area, convex hull area, compactness, roundness, and maximum length values for each object in the image.

Usage

find.shape(image, pix.min = 4000, scaledown = 4, colorcard = "bottomright")

Arguments

image	The image to be processed, must be a JPEG
pix.min	is number of pixels expected for the smallest object to be designated a tuber
scaledown	by which image is divided for faster computing (a reduction in image size)
colorcard	= NULL/"bottomright" to remove a color card if used

Value

A nested list with the BB width, BB length, perimeter, convex perimeter, area, convex hull area, compactness, roundness, and maximum length values for each object.

Examples

  find.shape(system.file("images", "2020fy2_317.jpg", package = "TubAR"))
  find.shape(system.file("images", "2020fy2_317.jpg", package = "TubAR"), pix.min=4e4, scaledown=5, colorcard="bottomright")
