Chain code scheme is one of the Picture Description Languages used to represent lines. This paper focuses on the line drawing interpretation by utilising closed loop chain code algorithm as a tool in deriving two geometric entities, i.e. T-junction and region, of a two-dimensional line drawing sketch. The closed loop chain code algorithm assumes that the sketch represents a three-dimensional solid object. The algorithm is based on 8-connected 3Â°â€”3 windows of Freeman chain code. Two factors determine the success of the algorithm. The first factor is the direction of traverses either clockwise or anti-clockwise. The other is the start location of the 3Â°â€”3 window traverse. This paper explains these factors and their applications in deriving the geometric entities. The discussion is supported with an example of L-block object for clarification in the presentation of the algorithm. The paper is concluded with conclusion and future works.
