skimage.filters.rank.percentile(image, selem, out=None, mask=None, shift_x=False, shift_y=False, p0=0)
[source] -
Return local percentile of an image.
Returns the value of the p0 lower percentile of the local greyvalue distribution.
Only greyvalues between percentiles [p0, p1] are considered in the filter.
Parameters: image : 2-D array (uint8, uint16)
Input image.
selem : 2-D array
The neighborhood expressed as a 2-D array of 1’s and 0’s.
out : 2-D array (same dtype as input)
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 structuring element center point. Shift is bounded to the structuring element sizes (center must be inside the given structuring element).
p0 : float in [0, ..., 1]
Set the percentile value.
Returns: out : 2-D array (same dtype as input image)
Output image.
