Describes the theory and practice of the computer interpretation of line images and demonstrates how line drawing interpretation systems can be developed. The book shows how problems are tackled and provides an overview of processes underpinning interpretation of images of line drawings.
The Line Drawing Interpretation Problem: Motivation.- Manual Input vs Document Scanning.- Raster-Based vs Symbolic Representations Engineering Drawings and Maps.- Line Drawing Interpretation, Image Understanding and Pattern Recognition.- Current Line Drawing Interpretation Systems.- The Line Drawing Interpretation Literature.- Components of a Line Drawing Interpretation System: Design Criteria for Drawing Interpretation Systems.- Five Stages of Line Drawing Interpretation.- Intermediate and Target Representations.- Systems Architectures and the Role of A Priori Knowledge.- Document Image Acquisition: Scanning Devices.- Image Coding.- Image File Formats.- Binarisation: A Taxonomy of Thresholding Techniques.- Document Image Statistics.- Binarising Line Drawings.- Binary Image Processing and the Raster to Vector Transformation: Raster to Vector Conversion.- Some Definitions.- The Distance Transform.- Mathematical Morphology.- Reducing Noise in Binary Images.- Reducing Noise in Binary Images of Line Drawings.- Analysis of Connected Components: Nomenclature.- Contouring.- Skeletonisation.- Grey-Level Skeletonisation.- Vectorisation: Approaches to Vectorisation.- Global Vectorisation Methods.- Local Vectorisation Methods.- The Hough Transform.- Direct Vectorisation.- A Vector Database.- Removing Noise from the Vector Model.- Alternative Raster-to-Vector Technologies.- Interpreting Images of Maps: Introduction.- Systems Overview.- Map Interpretation Principles.- A Classification of Map Entities.- Interactive Map Interpretation.- Output Formats.- Quality Issues.- Recognising Cartographic Objects: Recognising Isolines.- Recognising Roads.- Recognising Texture and Area Objects.- Recognising Symbols.- Recovering Engineering Drawing Entities from Vector Data: Design Principles and System Architecture.- Vectorisation and Entity Recognition Processes.- Extracting Arcs and Straight Lines.- Recognising Crosshatched Areas.- Recognising Dimensions.- Detecting Blocks.- Knowledge-Directed Interpretation of Engineering Drawings: An Image Understanding Approach.- Drawing Entities as Schemata.- Image Analysis Facilities.- The ANON Architecture.- Control Issues.- Entity Extraction: Chained Lines.- Top-Down and Bottom-Up Control.- Performance.- Scene Formation.- ANON in Context.- Discussion.- Output and Conclusions: Draughting Digitised Information.- Other Applications of Line Drawing Interpretation.- Topics for Further Development.- References.- Index.
