Equivalent to Nuke's pixel analyzer? (Way to see values of darkest/lightest pixels in frame?)

Is there a tool in AE that will identify the RGBA values of the brightest (max), darkest (min), and preferably median and mean pixels in a frame (or a selection)--like Nuke's Pixel Analyzer? Info is only of moderate utility in this regard since it is only for a pixel, not for a whole frame, and thus depends on exact picker-picking.
