摘要：

Calculations are presented of the errors encountered when the lengths of arbitrarily directed straight lines are measured directly by means of several encoding schemes. Ways in which the measurement errors may be diminished are examined; the simplest is to make an allowance for the number of corners that appear when a line is represented by a 4-way code. The efficiencies of the various coding schemes are examined and the 4-way code is found to be the most efficient of the close-neighbors coding schemes, although efficiency can be further increased by use of a generalized code. © 1979 Academic Press, Inc.
