Canny　edge　detector　is　the　Most　popular　tool　for　edge　detection　and　has　many　applications　in　the　areas　of　image　processing,　multimedia　and　computer　vision.　The　Canny　algorithm　optimizes　the　edge　detection　through　noise　filtering　using　an　optimal　function　approximated　by　the　first　derivative　of　a　Gaussian.　It　identifies　the　edge　points　by　computing　the　gradients　of　light　intensity　function　based　on　the　fact　that　the　edge　points　likely　appear　where　the　gradient　magnitudes　are　large.　Hexagonal　structure　is　an　image　structure　alternative　to　traditional　square　image　structure.　Because　all　the　existing　hardware　for　capturing　image　and　for　displaying　image　are　produced　based　on　square　structure,　an　approach　that　uses　linear　interpolation　described　for　conversion　between　square　and　hexagonal　structures.　Gaussian　filtering　together　with　gradient　computation　is　performed　on　the　hexagonal　structure.　The　pixel　edge　strengths　on　the　square　structure　are　then　estimated　before　the　thresholds　of　Canny　algorithm　are　applied　to　determine　the　final　edge　map.　The　experimental　results　show　the　edge　detection　on　hexagonal　structure　using　static　and　video　images,　and　the　comparison　with　the　results　using　Canny　algorithm　on　square　structure.
