“…It has been done mostly by using temporal (dynamic) information recovery techniques such as contour analysis [24], [25], gray-scale examination [26], [27], and path minimization [28], [29], [30]. Other methods include thinning/skeletonization [31], [32], [33], [34], [35], [36], [37], [38], [39] and morphological loop investigation [40], [41], [42]. This paper improves aspects of former solutions; we detect and resolve the structure of most loops.…”
