This paper presents a method for improving the accuracy of template-based planar tracking. It has been shown that when the ROI of the input image has a lower resolution than the template, tracking accuracy will deteriorate; then, this can be remedied by blurring the template in response to the motion of the plane. In this study, we show that, conversely, when the template has a lower resolution...

background: increasing frame rate is a challenging issue for better interpretation of medical images and diagnosis based on tracking the small transient motions of myocardium and valves in real time visualization. methods: in this paper, manifold learning algorithm is applied to extract the nonlinear embedded information about echocardiography images from the consecutive images in two dimension...
