figure_detectAxis: Detect an axis from a figure image.

In metagear: Comprehensive Research Synthesis Tools for Systematic Reviews and Meta-Analysis

Description

Attempts to detect either the X (horizontal) or Y (vertical) axis from a plotted figure.

Attempts to detect either the X (horizontal) or Y (vertical) axis from a plotted figure.

Usage

figure_detectAxis(
  aBinaryPlot,
  axis_type = "X",
  axis_thickness = 5,
  sensitivity = 0.2
)

figure_detectAxis(
  aBinaryPlot,
  axis_type = "X",
  axis_thickness = 5,
  sensitivity = 0.2
)

Arguments

aBinaryPlot	A binary figure image (an EBImage object). See: figure_transformToBinary
axis_type	The axis to be detected from a figure: can be X or Y.
axis_thickness	An integer used to designate the thickness of the axis lines on a figure. Close alignment to the thickness of the axis on a figure will improve axis detection.
sensitivity	A value designating the sensitivity of identifying straight lines on a figure. A smaller number results in a higher sensitivity to identify axes.

Value

An EBImage object with detected points.

An EBImage object with detected points.
