medianBlur

medianBlur

Blurs an image using the median filter.

C++: void medianBlur(InputArray src, OutputArray dst, int ksize)

Python: cv2.medianBlur(src, ksize[, dst]) → dst

Parameters:	src – input 1-, 3-, or 4-channel image; when ksize is 3 or 5, the image depth should be CV_8U, CV_16U, or CV_32F, for larger aperture sizes, it can only be CV_8U. dst – destination array of the same size and type as src. ksize – aperture linear size; it must be odd and greater than 1, for example: 3, 5, 7 ...

The function smoothes an image using the median filter with the  aperture. Each channel of a multi-channel image is processed independently. In-place operation is supported.
