Article Synopsis
- A two-stage segmentation algorithm is developed to address challenges in MRI images, such as inhomogeneity, weak edges, and artifacts.
- The first stage uses K-mean clustering for object classification, followed by defining a speed function to identify rough boundaries, while the second stage improves boundary accuracy using gradient intensity.
- A deformable model reconstructs the shape of the left ventricle (LV) by considering external forces from MRI slices and using the level set method to solve the governing dynamic equations, proving the algorithm's effectiveness through experiments.
