In this paper an efficient cardiac view classification of echocardiogram is proposed. A cardiac cycle consists of two phases systolic and diastolic. The systolic is the contraction and diastolic is relaxation and filling. From the given video sequences only the diastolic frames are extracted and it is utilized for determining the view of the echocardiogram. The Echocardiogram image are first prepared to reduce noise and to enhance the contrast of the image then mathematical morphology is used to highlight the cardiac cavity before segmentation using Connected Components Labeling (CCL) is carried out. We classify three standard cardiac views namely parasternal short axis (PSAX), apical two chamber (A2C) and four chamber (A4C) views. Experiments over 200 echocardiogram images show that the proposed method ascertains 94.56% of accuracy in cardiac view classification.
