Other AbstractTraditional subpixel edge location algorithms use local model to realize precise edge location.Which leads to side effects such as Zigzag effect and discontinuous edges.We present a new subpixel edge location algorithm based on partial differential equation(PDE),where level—set reconstruction(LSR)is introduced to smooth edge along their tangents.Anchor and topology constraints are used to avoid over—smoothing and keep edge topology structures.Subpixel edge location experiments with both geometric and natural image show that this method can remove zigzag effect while keeping edge smoothness and continuity.
