ABSTRACT

The comparison of different types of line and boundary detectors is made. The
appropriate modifications of procedures for processing of grey level or binary images
are analysed. The accuracy and quality of contours generated from images with
different resolution are estimated. Different procedures for line following and contour
interpolation for structural description of vector information obtained from digital
images are compared. The properties of these procedures are encountered and the
criteria for choice of the appropriate procedure are formulated. The suggested
approaches and procedures are suitable for implementation in the software packages for
digital processing of graphic and text images. The final result is presentation of data in
vector form. Such procedure is suitable for automatic generation of information that is
utilised in computer aided design systems.
