Image processing and analysis techniques for reading kinetheodolite film scales

This report describes a series of techniques for processing and analyzing images. Although developed for a specific purpose, namely the automatic reading of angular information on Askania kinetheodolite film, most of the techniques are quite general, and potentially applicable to a wide variety of problems. The processes described include real time binarisation of a television signal, production and analysis of projections to determine the positions of features of interest, and character recognition.
