In CeMOS-Mannheim/PlaquePicker: Single-object based analysis of MSI data

Unimodal threshold based on geometric method

Description

Calculates a threshold for unimodal distribuated values based on histogram thresholding. Implementation of Rosin, P. L. (2001). "Unimodal thresholding." Pattern Recognition 34(11): 2083-2096. A line is drawn between the bin with the highest frequency and the bin with the highest intensity/value (main line). After for each bin another line, orthogonal to the first line, is drawn to the "top" of each bin. The value of the bin with the longst distance to the main line is defined as threshold

Usage

geometricThreshold(intensities, breaks = 500, plot = FALSE)

Arguments

intensities	Vector of intensities.
breaks	Number of bins of the histogram.
plot	Plots the internally generated plot.

Value

Threshold value (see description)
