Specifies the size of the median filter as radius in pixels, excluding the center pixel.
The filter is applied to the disparity map. Median filtering will reduce noise inside surfaces while maintaining sharp edges, but object corners will be rounded.
An integer specifying half the median filter window size in pixels, excluding the center pixel. Allowed values are 0 to 10.
Setting the filter radius to 0 will disable median filtering.
With a radius of 3 pixels or higher, the filter might take significantly longer than with a lower radius.
