Freeman Encoding Based on Thinned Drawings

  title={Freeman Encoding Based on Thinned Drawings},
  author={Xiao Tao Ju},
In the process of vectoring engineering drawings,straight-line segments are the most prominent constituent,and many high level constituent parts as curves can be mimicked by line-segments approximation,so recognition for line-segments is the most important stage in vectorization.The Freeman encoding for lines is applied to the recognition for straight-line segments in the thinned scanning-drawings.We provide a way to turn pix to line-segments.
