Takes a binary image and detects the border between the white multiple features and the black background. After taking these coordinates, they will be sorted such that a closed border will be in either clockwise, anti-clockwise or unsorted. These sets of borders can then be classified into whole features with all borders internal or external to the feature.
A previously missing program has been included in this new update. (16 Dec 2003)
