`skimage.filters.thresholding:apply_hysteresis_threshold`

source: /dev/scikit-image/src/skimage/filters/thresholding.py:1183

Signature

def apply_hysteresis_threshold(image, low, high)

Summary

Apply hysteresis thresholding to image.

Extended Summary

This algorithm finds regions where image is greater than high OR image is greater than low and that region is connected to a region greater than high.

Parameters

image : (M[, ...]) ndarray: Grayscale input image.
low : float, or array of same shape as ``image``: Lower threshold.
high : float, or array of same shape as ``image``: Higher threshold.

Returns

thresholded : ndarray of dtype bool and shape (M[, ...]): Array in which True indicates the locations where image was above the hysteresis threshold.

Examples

image = np.array([1, 2, 3, 2, 1, 2, 1, 3, 2])
apply_hysteresis_threshold(image, 1.5, 2.5).astype(int)
