This paper presents experimental results and analysis for a study of the effect of de-noising on the consistency and reliability of manually-defined borders of echocardiograms. De-Noising and image enhancement have been performed on a test data set of 60 sequences from an echocardiographic database exhibiting diverse image quality. Both endocardial and epicardial borders of end diastolic and end systolic frames were manually identified for original and enhanced images based on image perception and wall motion information. Statistical analysis was performed on the identified borders. The experimental results show that de-noising and image enhancement help to improve the consistency of the manually- defined borders for the data set. |
