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

Table 6

Comparison and evaluation of contours acquired from manual delineation of fused image and input image. The outcomes present a high similarity among them; it means endocardial contours stay stable after fusion and do not displaced through the combination procedure.

	Input image versus fused image
DSI [mean ± std]	0.89 ± 0.03
[mean ± std]	0.95 ± 0.34
