Segmentation of echocardiographic images presents a great challenge because these images contain strong speckle noise and artifacts. Besides, most ultrasound segmentation methods are semi-automatic, requiring initial contour to be manually identified in the images. In this work, we propose an algorithm based on the phase symmetry approach and level set(More)
Ultrasonography is one of the safest methods in medical imaging, however the segmentation of such images still is a difficult task. A robust segmentation of the heart cavities and a 3D view are needed to better understand the congenital malformations and defects in children hearts. In this work we propose an automatic segmentation method based on geometric(More)
