Abstract According to the automation and general requirements of parameterized curve set regions identification algorithm, spatial organization
of regions generated by parameterized curve set is represented using multi-tree structure. Based on the establishment of directional closed loops, a
new method for identification of complex regions is proposed for the automation and general applicability. Compared with the other methods, this
method is effective for regions with holes and islands. It has wide adaptability and is easy to implement.
Key words parameterized curve; region identification; multi-tree; directional closed loop
