`skimage.filters.rank._percentile:threshold_percentile`

source: /dev/scikit-image/src/skimage/filters/rank/_percentile.py :441

Signature

   def     threshold_percentile (    image    ,    footprint    ,    out    =  None   ,    mask    =  None   ,    shift_x    =  0   ,    shift_y    =  0   ,    p0    =  0     )

Summary

Local threshold of an image.

Extended Summary

The resulting binary mask is True if the grayvalue of the center pixel is greater than the local mean.

Only grayvalues between percentiles [p0, p1] are considered in the filter.

Parameters

image : 2-D array (uint8, uint16): Input image.
footprint : ndarray of shape (m, n): The neighborhood expressed as a 2-D array of 1's and 0's.
out : 2-D array, same dtype as input `image`: If None, a new array is allocated.
mask : ndarray: Mask array that defines (>0) area of the image included in the local neighborhood. If None, the complete image is used (default).
shift_x, shift_y : int: Offset added to the footprint center point. Shift is bounded to the footprint sizes (center must be inside the given footprint).
p0 : float, optional, in interval [0, 1]: Set the percentile value.

Returns

out : 2-D array, same dtype as input `image`: Output image.
