Function dilate

pub fn dilate(
    src: &impl GMatTraitConst,
    kernel: &impl MatTraitConst,
    anchor: Point,
    iterations: i32,
    border_type: i32,
    border_value: Scalar,
) -> Result<GMat>

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:

Dilation can be applied several (iterations) times. In case of multi-channel images, each channel is processed independently. Supported input matrix data types are [CV_8UC1], [CV_8UC3], [CV_16UC1], [CV_16SC1], and [CV_32FC1]. Output image must have the same type, size, and number of channels as the input image.

Note:

• Rounding to nearest even is procedeed if hardware supports it, if not - to nearest.
• Function textual ID is “org.opencv.imgproc.filters.dilate”

Parameters

• src: input image.
• kernel: structuring element used for dilation; if elemenat=Mat(), a 3 x 3 rectangular structuring element is used. Kernel can be created using getStructuringElement
• 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 cv::BorderTypes
• borderValue: border value in case of a constant border
