In Bott-binc/magnetoPackage2020: The building blocks for digitization of magnetograms, or images alike

Finding Peaks for Image

Description

Finds peaks in the row sums of an image matrix, used for finding starts of lines that are horizontal

Usage

find_peaks(
  rowSums,
  minDistance,
  maxPeakNumber,
  percentFromEdge,
  percentEdgeForLeft = NULL,
  minPeakHeight = (0.05 * max(rowSums)),
  plots = TRUE,
  StartEndplotLine = TRUE
)

Arguments

rowSums	of the imported matrix from original picture
minDistance	Minimum distance aloud between found peaks
maxPeakNumber	Maximum peaks you are trying to find
percentFromEdge	Percentage of the picture that you would like removed from edge due to an over exposed picture or flares in scanning if percentageLeftSide is unspecified uses percentage for both i.e left = 1 - right
percentEdgeForLeft	the left percentage that you want to remove(default = NULL)
minPeakHeight	minimum peak height required for a peak to be counted Default is 5perc of the max(rowSums)
plots	Plots the peaks on rowSums
StartEndplotLine	If you want to see lines at start and ends of each peaks (starts are green, ends are blue)

Value

data frame of peaks, peak heights, starts and ends for each peak
