import { gapi_dilate } from '@banou/opencv-wasm'Use after await initOpenCV(). See the initialization and named imports guide.
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:
\texttt{dst} (x,y) = \max _{(x',y'): \, \texttt{element} (x',y') \ne0 } \texttt{src} (x+x',y+y')
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"

kernelstructuring element used for dilation; if elemenat=Mat(), a 3 x 3 rectangular structuring element is used. Kernel can be created using getStructuringElement
anchorposition of the anchor within the element; default value (-1, -1) means that the anchor is at the element center.
