Echocardiographic image sequence segmentation by multiscale directional snake

Echocardiographic image sequence segmentation by multiscale directional snake

In this paper, a new algorithm named as ‘multiscale directional snake’ is proposed for segmentation of chocardiographic images by computer. The method makes use of morphological operations to locate the left ventricular center point and region of interest. In addition,...

School of Electrical and Electronic Engineering IEEE International Symposium on Signal Processing and Information Technology (4th : 2004 : Rome, Italy) In this paper, a new algorithm named as ‘multiscale directional snake’ is proposed for segmentation of chocardiographic images by computer. The method makes use of morphological operations to locate the left ventricular center point and region of interest. In addition, a multiscale directional edge map is introduced to improve the performance of snake. The snake is confined within the region of interest during deformation and does not require initialization like traditional snake. Results show that the boundaries obtained using the proposed method fit very closely to the manually traced boundaries.
