Its a blood vessel My aim is to segment the blood vessel and to identify whether the flow through the blood vessel is normal or abnormal (due to occlusion) from the extracted features from the segmented region normal: http://upload.wikimedia.org/wikipedia/commons/c/c0/SpectralDopplerA.jpg abnormal: http://schools.medphys.ucl.ac.uk/images/ultrasound/ultrasound_blocked_carotid.jpg "Dave Robinson" <dave.robinson(a)somewhere.biz> wrote in message <hov349$h52$1(a)fred.mathworks.com>... > "ag " <startler.ag(a)gmail.com> wrote in message <hov2hg$3g8$1(a)fred.mathworks.com>... > > I want to segment carotid artery from its ultrasound image.
