| Summary: | 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. |
