方框滤波

void cv::boxFilter     (     InputArray      src,
        OutputArray      dst,
        int      ddepth,
        Size      ksize,
        Point      anchor = Point(-1,-1),
        bool      normalize = true,
        int      borderType = BORDER_DEFAULT
    )         
Python:
    dst    =    cv.boxFilter(    src, ddepth, ksize[, dst[, anchor[, normalize[, borderType]]]]    )

 

 

 Parameters

src	input image.
dst	output image of the same size and type as src.
ddepth	the output image depth (-1 to use src.depth()).
ksize	blurring kernel size.
anchor	anchor point; default value Point(-1,-1) means that the anchor is at the kernel center.
normalize	flag, specifying whether the kernel is normalized by its area or not.
borderType	border mode used to extrapolate pixels outside of the image, see BorderTypes. BORDER_WRAP is not supported.
