Hybrid Pixel-Based Method for Cardiac Ultrasound Fusion Based on Integration of PCA and DWT

Table 4

Failure of segmentation technique on fused and input echocardiograms and its particular quantification. The outcomes are demonstrated for 10 subjects. As explained before, segmentation failing means the inability of the segmentation algorithm to achieve the actual endocardial border caused by border loss, noise of cavity, or both equally.
