1. 1. Digital straight line segments and curves

   Författare :Shiva Samieinia; Stockholms universitet; []
   Nyckelord :Digital geometry; digital straight line segments; chord property; Khalimsky-continuous function.;

   Sammanfattning : This thesis consists of two papers:Paper A. Chord properties of digital straight line segments.This paper treats digital straight line segments in two different cases, in the 8-connected plane and in the Khalimsky plane. We investigate them using a new classification, dividing them into a union of horizontal and diagonal segments. LÄS MER
