Trait ThresholdOtsuExt

pub trait ThresholdOtsuExt<T> {
    type Output;

    // Required method
    fn threshold_otsu(&self) -> Result<Self::Output, Error>;
}

Runs the Otsu thresholding algorithm on a type T.

Required Associated Types

type Output

The Otsu thresholding output is a binary image.

Required Methods

fn threshold_otsu(&self) -> Result<Self::Output, Error>

Run the Otsu threshold algorithm.

Due to Otsu threshold algorithm specifying a greyscale image, all current implementations assume a single channel image; otherwise, an error is returned.

Errors

Returns a ChannelDimensionMismatch error if more than one channel exists.
