Abstract :
A curve evolution approach is proposed for corner enhancement. The constraint is that a new corner should not be generated. Starting from the general geometric heat flow (GGHF), we study under what conditions the GGHF satisfies the scale space causality criteria. The criteria of corner enhancement are also proposed. Then, a new curve evolution scheme which can enhance strong corners, suppress noise and satisfies the scale space criteria is presented
