	==SmartMedian==		===SmartMedian===
	The filters MedianBlur and Quantile are so poor - at least if the surrounding box is large - because all pixel of the surrounding box have equal influence on the end result and unlike RemoveGrainHD (with suitable rank values) the more distant pixels play a more and more dominant role in the calculation of the median as the box radius increases. SmartMedian tries to resolve this problem by computing the median of a subsample of the surrounding box. restricting the sample, over which the median is taken, to pixels with values sufficiently close to the value of the center pixel. The variables radius, radius_y, yradius_y, xradius_u, yradius_u, xradius_v, yradius_v are used by SmartMedian as well and play the same role as in the other filters of this plugin. However, instead of the various rank variables, the variables pixels, pixels_y, pixels_u, pixels_v are used. These variables describe the size of the subsample. The inheritance rules are the same as for the variables rank, rank_y, rank_u, rank_v in the filter Quantile. Obviously, the size of the subsample must be smaller than the size of the box. Thus pixel_y <= (2radius_y + 1) (2yradius_y + 1), pixel_u <= (2radius_u + 1) * (2yradius_u + 1) and pixel_v <= (2radius_v + 1) * (2yradius_v + 1). Of course these variables must also be positive. If unreasonable values are specified fpr these variables, they are suitably adjusted. To describe the algorithm underlying the SmartMedian filter we restrict ourselves to the Y channel and let A(r) be the pixels from the surrounding box of the center pixel c with distance(p,c) = \|p - c\| <= r (p,c are the pixel values and not the coordinates). In the first step SmartMedian calculates the smallest R>=0 such that the size \|A(R)\| of the subsample A(R) exceeds the value of pixels_y, i.e. \|A(R)\|>= pixels_y. If the pixel c is from an area with unform color, then R=0. If c is a noisy pixel, then R will be quite large, but usually it is quite small, if the value of pixels_y is reasonable. It may very well happen, that \|A(R)\| > pixels_y. If pixel_y = (2radius_y + 1) * (2yradius_y + 1) (the maximal value), then the subsample A(R) is equal to the entire surrounding box. If pixels_y=1 (the minimal value) then R=0 because c ist always contained in A(0). In the second step SmartMedian calculates n-th smallest min(n,R) and the n-th largest pixel max(n,R) of the subsample A(R), where n = pixels_y/2 (with rounding to the upside). Finally c is clipped with respect to min(n,R) and max(n,R), i.e. c is replaced by min(max(n,R), max(min(n,R),c)). If \|A(R)\| = pixles_y then c is indeed replaced by the median of the subsample A(R), otherwise is only approximately the median. Obviously, if R=0 then min(n,R) = c = max(n,R) and c is left unchanged. The default value for pixels_y is 2 min(2radius_y + 1, 2yradius_y + 1), i.e. twice the default value for rank_y in RemoveGrainHD. Again the default value assures that no thin lines or curves through the center c are interrupted by SmartMedian. Compared with RemoveGrainHD the value of pixels_y should be twice the value of rank_y to have a similar preservation of detail. If the default values for rank_y and pixels_y are chosen, then RemoveGrainHD leaves many pixels unchanged, while SmartMedian changes most pixels at least a little. All in all SmartMedian is more aggressive than RemoveGrainHD and should yield better compression. To illuminate the above description, let us look at some concrete cases. There Quantile, RemoveGrainHD and SmartMedian are used with the default values radius_y = yradius_y = 2, rank_y = urank_y = 5, pixels_y = 10 if not specified otherwise.
