To　solve　the　problems　of　complexity　and　low　robustness　that　exist　in　present　image　shape　feature　detection　and　description　methods,　a　new　image　shape　feature　detection　and　description　method　is　proposed.　First,　salient　regions　are　detected　using　a　method　based　on　connected　component.　Then,　a　descriptor　composed　of　Hu＇s　moment　invariants　and　eccentricity　is　used　to　descript　the　detected　regions.　Experiments　show　its　effectiveness　and　robustness　to　translation,　rotation　and　scaling.　©　2011　IEEE.
