Segmentation of Myocardial Boundaries in Tagged Cardiac MRI Using Active Contours: A Gradient-Based Approach Integrating Texture Analysis

Table 1

Average number of each type of pixels (expressed in percentage of the average total number of pixels of each pixel class within manual generated myocardium surface) for each of the 6 considered time steps of the systole.

Systole Step	Step  1	Step  2	Step  3	Step  4	Step  5	Step  6
TP	87.2%	85.1%	81.4%	79.7%	82.1%	81.0%
FP	3.1%	2.9%	2.2%	2.1%	1.9%	2.1%
TN	92.1%	93.1%	89.3%	90.1%	94.3%	91.8%
FN	1.2%	1.6%	1.9%	2.3%	1.7%	2.1%
