Function dilate

pub fn dilate(
    src: &impl ToInputArray,
    dst: &mut impl ToOutputArray,
    kernel: &impl ToInputArray,
    anchor: Point,
    iterations: i32,
    border_type: i32,
    border_value: Scalar,
) -> Result<()>

Dilates an image by using a specific structuring element.

The function dilates the source image using the specified structuring element that determines the shape of a pixel neighborhood over which the maximum is taken:

The function supports the in-place mode. Dilation can be applied several ( iterations ) times. In case of multi-channel images, each channel is processed independently.

Parameters

• src: input image; the number of channels can be arbitrary, but the depth should be one of CV_8U, CV_16U, CV_16S, CV_32F or CV_64F.
• dst: output image of the same size and type as src.
• kernel: structuring element used for dilation; if element=Mat(), a 3 x 3 rectangular structuring element is used. Kernel can be created using get_structuring_element
• anchor: position of the anchor within the element; default value (-1, -1) means that the anchor is at the element center.
• iterations: number of times dilation is applied.
• borderType: pixel extrapolation method, see #BorderTypes. [BORDER_WRAP] is not suported.
• borderValue: border value in case of a constant border
