gapi_blur
import { gapi_blur } from '@banou/opencv-wasm'Use after await initOpenCV(). See the initialization and named imports guide.
Blurs an image using the normalized box filter.
The function smooths an image using the kernel:
\texttt{K} = \frac{1}{\texttt{ksize.width*ksize.height}} \begin{bmatrix} 1 & 1 & 1 & \cdots & 1 & 1 \\ 1 & 1 & 1 & \cdots & 1 & 1 \\ \hdotsfor{6} \\ 1 & 1 & 1 & \cdots & 1 & 1 \\ \end{bmatrix}
The call blur(src, ksize, anchor, borderType) is equivalent to boxFilter(src, src.type(), ksize, anchor, true, borderType).
Supported input matrix data types are CV_8UC1, CV_8UC3, CV_16UC1, CV_16SC1, 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.blur"
