skimage 0.17.2

ParametersRaisesReturns
_generate_random_colors(num_colors, num_channels, intensity_range, random)

Parameters

num_colors : int

Number of colors to generate.

num_channels : int

Number of elements representing color.

intensity_range : {tuple of tuples of ints, tuple of ints}, optional

The range of values to sample pixel values from. For grayscale images the format is (min, max). For multichannel - ((min, max),) if the ranges are equal across the channels, and ((min_0, max_0), ... (min_N, max_N)) if they differ.

random : np.random.RandomState

The random state to use for random sampling.

Raises

ValueError

When the intensity_range is not in the interval (0, 255).

Returns

colors : array

An array of shape (num_colors, num_channels), where the values for each channel are drawn from the corresponding intensity_range .

Generate an array of random colors.

Examples

See :

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
