Trait CannyEdgeDetectorExt

pub trait CannyEdgeDetectorExt<T> {
    type Output;

    // Required method
    fn canny_edge_detector(
        &self,
        params: CannyParameters<T>,
    ) -> Result<Self::Output, Error>;
}

Runs the Canny Edge Detector algorithm on a type T

Required Associated Types

type Output

Output type, this is different as canny outputs a binary image

Required Methods

fn canny_edge_detector( &self, params: CannyParameters<T>, ) -> Result<Self::Output, Error>

Run the edge detection algorithm with the given parameters. Due to Canny being specified as working on greyscale images all current implementations assume a single channel image returning an error otherwise.
