`skimage.filters.thresholding:threshold_yen`

source: /dev/scikit-image/src/skimage/filters/thresholding.py :407

Signature

def threshold_yen ( image = None , nbins = 256 , * , hist = None )

Summary

Return threshold value based on Yen's method. Either image or hist must be provided. In case hist is given, the actual histogram of the image is ignored.

Parameters

image : (M, N[, ...]) ndarray: Grayscale input image.
nbins : int, optional: Number of bins used to calculate histogram. This value is ignored for integer arrays.
hist : array, or 2-tuple of arrays, optional: Histogram from which to determine the threshold, and optionally a corresponding array of bin center intensities. An alternative use of this function is to pass it only hist.

Returns

threshold : float: Upper threshold value. All pixels with an intensity higher than this value are assumed to be foreground.

Examples

from skimage.data import camera
image = camera()
thresh = threshold_yen(image)
binary = image <= thresh
