%GRAYCOMATRIX?Create?gray-level?co-occurrence?matrix.
%???GLCMS?=?GRAYCOMATRIX（I）?analyzes?pairs?of?horizontally-adjacent?pixels?in

%??
%???‘Offset‘?????????A?p-by-2?array?of?offsets?specifying?the?distance?between
%????????????????????the?pixel-of-interest?and?its?neighbor.?Each?row?in?the
%????????????????????array?is?a?two-element?vector?[ROW_OFFSET?COL_OFFSET]
%????????????????????that?specifies?the?relationship?or?‘Offset‘?between?a
%????????????????????pair?of?pixels.?ROW_OFFSET?is?the?number?of?rows?between
%????????????????????the?pixel-of-interest?and?its?neighbor.??COL_OFFSET?is?the
%????????????????????number?of?columns?between?the?pixel-of-interest?and?its
%????????????????????neighbor.?For?example?if?you?want?the?number?of
%????????????????????occurrences?where?the?pixel?of?interest?is?one?pixel?to?the
%????????????????????left?of?its?neighbor?then?[ROW_OFFSET?COL_OFFSET]?is?
%????????????????????[0?1].
