Automatic border detection of cardiac cavity images using boundary and triangle equation

In this paper, an automatic border detection of cardiac cavity in two-dimensional short axis echocardiography image is proposed. The method uses boundary and triangle equation to detect and reconstruct the border. The first step is determining the initial centers boundary. The second step is applying morphological and thresholding operations to eliminate noise and convert it into binary image. The last step is using boundary and triangle equation to detect and reconstruct the imprecise border. This technique can detect centers of boundary and border very precisely.
