Function opencv::imgproc::blur

pub fn blur(
    src: &dyn ToInputArray, 
    dst: &mut dyn ToOutputArray, 
    ksize: Size, 
    anchor: Point, 
    border_type: i32
) -> Result<()>

Blurs an image using the normalized box filter.

The function smooths an image using the kernel:

The call blur(src, dst, ksize, anchor, borderType) is equivalent to boxFilter(src, dst, src.type(), ksize, anchor, true, borderType).

Parameters

• src: input image; it can have any number of channels, which are processed independently, but the depth should be CV_8U, CV_16U, CV_16S, CV_32F or CV_64F.
• dst: output image of the same size and type as src.
• ksize: blurring kernel size.
• anchor: anchor point; default value Point(-1,-1) means that the anchor is at the kernel center.
• borderType: border mode used to extrapolate pixels outside of the image, see #BorderTypes. #BORDER_WRAP is not supported.

C++ default parameters

• anchor: Point(-1,-1)
• border_type: BORDER_DEFAULT
