%?DISPFEAT?-?Displays?feature?types?as?detected?by?PHASECONG.
%
%?This?function?provides?a?visualisation?of?the?feature?types?as?detected
%?by?PHASECONG.
%
%?Usage:??im?=?dispfeat(ft?edgeim?‘l‘)
%
%?Arguments:??ft?????-?A?complex?valued?image?giving?the?weighted?mean?
%??????????????????????phase?angle?at?every?point?in?the?image?for?the?
%??????????????????????orientation?having?maximum?energy.
%?????????????edgeim?-?A?binary?edge?image?(typically?obtained?via
%??????????????????????non-maxima?suppression?and?thresholding).
%??????????????????????This?is?used?as?a?‘mask‘?to?specify?which?bits?of
%??????????????????????the?phase?data?should?be?displayed.
%??????????????????????Alternatively?you?can?supply?a?phase?congruency
%??????????????????????image?in?which?case?it?is?used?to?control?the
%??????????????????????saturation?of?the?colour?coding
%?????????????l??????-?An?optional?parameter?indicating?that?a?line?plot
%??????????????????????encoded?by?line?style?should?also?be?produced.?If
%??????????????????????this?is?the?case?then?‘edgeim‘?really?should?be?an
%??????????????????????edge?image.
%?
%?Returns:????im?????-?An?edge?image?with?edges?colour?coded?according?to
%??????????????????????feature?type.?
%
%?Two?or?three?plots?are?generated:
%?1.?An?edge?image?with?edges?colour?coded?according?to?feature?type.
%?2.?A?histogram?of?the?frequencies?at?which?the?different?feature?types
%????occur.
%?3.?Optionally?a?black/white?edge?image?with?edges?coded?by?different?line
%????styles.??Not?as?pretty?as?the?first?plot?but?it?is?something?that?can
%????be?put?in?a?paper?and?reproduced?in?black?and?white.
