Metrication Errors and Coding Efficiency of Chain-Encoding Schemes for the Representation of Lines and Edges.
Abstract
Errors associated with several boundary encoding schemes are discussed in terms of average errors encountered when using the schemes directly for measurement of the lengths of arbitrarily directed straight lines. 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.
