Modelling and Testing the Stability of Edge Segments: Length and Orientation

  • Henrik Iskov ChristensenAalborg
  • Published 1995


This paper derives a model for the variance in the length and orientation of edge segments extracted from an image. It is assumed that edge pixel positions are subject to noise. The eeect of this positional uncertainty is propagated all the way to segment length and orientation. The model predicts an approximately constant variance in segment length… (More)
