Provided methods

pub fn detect(
    &mut self,
    image: &dyn ToInputArray,
    edges: &mut dyn ToOutputArray,
    stream: &mut Stream
) -> Result<()>[src]

Finds edges in an image using the Canny86 algorithm.

Parameters

  • image: Single-channel 8-bit input image.
  • edges: Output edge map. It has the same size and type as image.
  • stream: Stream for the asynchronous version.

C++ default parameters

  • stream: Stream::Null()

pub fn detect_1(
    &mut self,
    dx: &dyn ToInputArray,
    dy: &dyn ToInputArray,
    edges: &mut dyn ToOutputArray,
    stream: &mut Stream
) -> Result<()>[src]

Finds edges in an image using the Canny86 algorithm.

Parameters

  • image: Single-channel 8-bit input image.

Overloaded parameters

  • dx: First derivative of image in the vertical direction. Support only CV_32S type.
