Multi-Scale Blur Estimation and Edge Type Classification for Scene Analysis

  title={Multi-Scale Blur Estimation and Edge Type Classification for Scene Analysis},
  author={Wei Zhang and Fredrik Bergholm},
  journal={International Journal of Computer Vision},
Signatures, in this work, are multi-scale representations of local gray-level information, tied to places in gray scale images where regional differences are locally maximal. The information may involve the regional differences themselves (called Gaussian differences or signed normalized gradient magnitudes, (Korn, 1988)), or, distance relations between edges (apparent width measurements), or, absence of edges in pulse edge pairs, at coarser scales. Using signatures involves the classical… CONTINUE READING
