Extracting System-Level Understanding from Wiring Diagram Manuals global representation of the full set of electrical connections in an aircraft. To fully understand the nature of a link between diagrams, the system must not only parse the link itself, but also determine the surrounding graphical context and discover exactly what object in the target diagram is b

Automatic Generation of Layered Illustrated Parts Drawings for Advanced Technical Data Systemsthousands of illustrated parts drawings that must be transformed into richer, more intelligent formats for use in advanced technical data systems. Because manually re-authoring the drawings is prohibitively expensive, our solution is to provide a batch-processing system that automatically transforms

Main Wall Recognition of Architectural Drawings Using Dimension Extension Lineby two parallel bold lines, symbols(door, window, tile...), dimension line, extension line, and dimensions represent various numerical values and characters. This paper suggests a method for recognizing main wall which is a back-bone of apartment in an architectural drawing. In this thesis, the foll

Skewed Mirror Symmetry for Depth Estimation in 3D Line-Drawingsror symmetry detected in such sketches. Taking account of mirror symmetry of such polyhedra can significantly improve the reconstruction process. Applying symmetry as a regularity in optimisation-based reconstruction is shown to be adequate by itself, without the need for other inflation techniques

Vectorial Signatures for Symbol Discriminationcal documents. Considering a raw vectorial description of the graphical layer of a technical document, we have based our approach on a method proposed by Etemadi et al. The signature of all models of symbols that could be found in a given document are computed and matched against the signature of th

Syntactic Models to Represent Perceptually Regular Repetitive Patterns in Graphic Documents symbols and they usually contain hatched or tiled patterns. Our grammar-based models can be automatically inferred from the document and used as signatures to describe salient features consisting of regular repetitions of primitives. These signatures compactly describe texture symbols and its primi

Indexing Technical Symbols Using Ridgelets Transformorm is useful to detect linear singularities in images. Therefore, it can be used to get a good representation of linear symbols. Moreover, as it belongs to the Wavelet family, this representation can be useful at several scales of detail. Thus, the proposed scheme targets to detect linear singulari
