Segmentation Echocardiography Video Using B-Spline and Optical Flow

In this paper, a segmentation echocardiography video using B-Spline and Optical Flow is proposed. The method used median filtering, b-spline and optical flow. The first step is applying Median Filter to eliminate noise. The second step is B-Spline to determining the initial boundary of the cardiac cavity in the first frame. The third step is using Optical Flow method to detect and tracking the border for every frame in echocardiography video. It can be seen that error between system and average of users is only less than 11 % and the area of cardiac cavity almost same with the average standard deviation is 0.18. This indicates that this method is effective to tracking cardiac cavity in echocardiography video.
