MakeExpression[boxes, form] is the low-level function used in Mathematica sessions to construct expressions from boxes.
MeanShiftFilter[image, r, d] replaces each pixel with the mean of the pixels in a range-r neighborhood and whose value is within a distance d.MeanShiftFilter[array, r, d] ...
MeanShift[list, d] replaces each element in list by the mean of the values of all elements that differ by less than d.
NotebookConvertSettings -> {opt_1 -> val_1, opt_2 -> val_2, ...} is a global option that specifies settings for converting imported legacy notebooks.
OpenRead["file"] opens a file to read data from, and returns an InputStream object.
OrderedQ[h[e_1, e_2, ...]] gives True if the e_i are in canonical order, and False otherwise.
Placed
(Built-in Mathematica Symbol) Placed[expr, pos] represents an expression expr placed at relative position pos in a chart or other display. Placed[{e_1, e_2, ...}, pos] places each of the e_i at a relative ...
