figure_detectAllPoints(
  aBinaryPlot,
  sensitivity = 0.2,
  point_shape = "circle",
  point_size = 5
)

Arguments

aBinaryPlot

A binary figure image (an EBImage object). See: figure_transformToBinary

sensitivity

A value designating the sensitivity of identifying unique points that overlap. A smaller number results in a higher sensitivity to split overlapping points; a larger number will extract only a single point from a cluster of overlapping points.

point_shape

The shape of points on figure: can be "circle", "square", or "diamond". If these options do not fit the shape found in a figure, use the option that best approximates that shape.

point_size

An integer used to designate the size of the points on the figure. Close alignment to the size of the points on a figure will improve point detection. See EBImage to help determine which size to use.

Value

An EBImage object with detected scatter-plot points.
