Paper Abstract

This paper describes the problem of labeling and completing an imperfect line drawing. Almost all of techniques about shape from contour require a perfect line drawing as their input. Experience indicates, however, that lines are often missing. We exhaustively studied all possible configurations of the imperfect line drawing and found that it is closely related to L-junction. W and Y-junctions in the imperfect line drawings are the same as they are in a perfect line drawing, L-junctions, however, are different because they could be degenerated from W or Y ones. In this paper, it is shown that the number of L-junction in the imperfect line drawing is 36. The 36 L-junctions and their corresponding W or Y ones from which they are degenerated are illustrated. We show how to utilize the line labeling and junction to predict and complete missing line.
