%?SLIC?Superpixels
%
%?Usage:???[l?Am?Sp?d]?=?slic（im?k?m?seRadius?colopt?mw）
%
%?Arguments:??im?-?Image?to?be?segmented.
%??????????????k?-?Number?of?desired?superpixels.?Note?that?this?is?nominal
%??????????????????the?actual?number?of?superpixels?generated?will?generally
%??????????????????be?a?bit?larger?espiecially?if?parameter?m?is?small.
%??????????????m?-?Weighting?factor?between?colour?and?spatial
%??????????????????differences.?Values?from?about?5?to?40?are?useful.??Use?a
%??????????????????large?value?to?enforce?superpixels?with?more?regular?and
%??????????????????smoother?shapes.?Try?a?value?of?10?to?start?with.
%???????seRadius?-?Regions?morphologically?smaller?than?this?are?merged?with
%??????????????????adjacent?regions.?Try?a?value?of?1?or?1.5.??Use?0?to
%??????????????????disable.
%?????????colopt?-?String?‘mean‘?or?‘median‘?indicating?how?the?cluster
%??????????????????colour?centre?should?be?computed.?Defaults?to?‘mean‘
%?????????????mw?-?Optional?median?filtering?window?size.??Image?compression
%??????????????????can?result?in?noticeable?artifacts?in?the?a*b*?components
%??????????????????of?the?image.??Median?filtering?can?reduce?this.?mw?can?be
%??????????????????a?single?value?in?which?case?the?same?median?filtering?is
%??????????????????applied?to?each?L*?a*?and?b*?components.??Alternatively?it
%??????????????????can?be?a?2-vector?where?mw（1）?specifies?the?median
%??????????????????filtering?window?to?be?applied?to?L*?and?mw（2）?is?the
%??????????????????median?filtering?window?to?be?applied?to?a*?and?b*.
%
%?Returns:?????l?-?Labeled?image?of?superpixels.?Labels?range?from?1?to?k.
%?????????????Am?-?Adjacency?matrix?of?segments.??Am（i?j）?indicates?whether
%??????????????????segments?labeled?i?and?j?are?connected/adjacent
%?????????????Sp?-?Superpixel?attribute?structure?array?with?fields:
%???????????????????L??-?Mean?L*?value
%???????????????????a??-?Mean?a*?value
%???????????????????b??-?Mean?b*?value
%???????????????????r??-?Mean?row?value
%???????????????????c??-?Mean?column?value
%???????????????????stdL??-?Standard?deviation?of?L*?
%???????????????????stda??-?Standard?deviation?of?a*?
%???????????????????stdb??-?Standard?deviation?of?b*?
%???????????????????N?-?Number?of?pixels
%???????????????????edges?-?List?of?edge?numbers?that?bound?each
%???????????????????????????superpixel.?This?field?is?allocated?but?not?set
%???????????????????????????by?SLIC.?Use?SPEDGES?for?this.
%??????????????d?-?Distance?image?giving?the?distance?each?pixel?is?from?its
%??????????????????associated?superpixel?centre.
%
%?It?is?suggested?that?use?of?this?function?is?followed?by?SPDBSCAN?to?perform?a
%?DBSCAN?clustering?of?superpixels.??This?results?in?a?simple?and?fast
