threshold_minimum(image, nbins=256, max_iter=10000)

The histogram of the input image is computed and smoothed until there are only two maxima. Then the minimum in between is the threshold value.

Parameters

image : (M, N) ndarray

Input image.

nbins : int, optional

Number of bins used to calculate histogram. This value is ignored for integer arrays.

max_iter : int, optional

Maximum number of iterations to smooth the histogram.

Raises

RuntimeError

If unable to find two local maxima in the histogram or if the smoothing takes more than 1e4 iterations.

Returns

threshold : float

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

Return threshold value based on minimum method.

Examples

This example is valid syntax, but we were not able to check execution
>>> from skimage.data import camera
... image = camera()
... thresh = threshold_minimum(image)
... binary = image > thresh

Local connectivity graph

Hover to see nodes names; edges to Self not shown, Caped at 50 nodes.

Using a canvas is more power efficient and can get hundred of nodes ; but does not allow hyperlinks; , arrows or text (beyond on hover)

SVG is more flexible but power hungry; and does not scale well to 50 + nodes.

All aboves nodes referred to, (or are referred from) current nodes; Edges from Self to other have been omitted (or all nodes would be connected to the central node "self" which is not useful). Nodes are colored by the library they belong to, and scaled with the number of references pointing them
