What is Active Appearance Model (AAM)

Echocardiography is the fastest, least expensive, and least invasive heart imaging method. Accordingly, it is one of the most commonly used techniques to quantify the ventricular systolic function in patients. The examination is based on visual analysis of myocardial wall motion and deformation by an experienced and trained physiologist. This investigation is subjective, experience dependent, and the obtained results are only partially quantitative. The segmentation of the measured image sequences focuses on finding the exact boundaries of particular objects of interest, but it usually requires manual assistance.
