The visualization of conceptual structures is a key component of support tools for complex applications in science and engineering. Foremost among the visual representations used are drawings of graphs and ordered sets. In this talk, we survey recent advances in the theory and practice of graph drawing. Specific topics include bounds and tradeoffs for drawing properties. tlrlce-dimensional Icpt...

In order to adapt the training objective of applied talents in higher vocational colleges, this paper embodies law knowledge and helps students build structure engineering drawing courses. This discusses a teaching model course suitable for online offline blended teaching, which is constantly explored practice, perfected deepened network resources, so that improved promoted provides new idea re...

Tables are compact and efficient to list or represent complex objects. Due to differences between tables in engineering drawings and other documents, series of new problems need to be considered. In this paper, we propose a Progressively-Normalized Cell Integration (PNCI) method to recognize and understand engineering tables.

In this paper, we propose a framework for engineering drawings recognition using a case-based approach. The key idea of our scheme is that, interactively, the user provides an example of one type of graphic object in an engineering drawing, then the system learns the graphical knowledge of this type of graphic object from the example and uses this learned knowledge to recognize or search for si...

In this paper a process visualisation development system and its associated development methodology are presented. This methodology is optimised to systems that have complex structure and are built of large number of components belonging to relatively small number of types. In order to handle the complexity, the input requirements of the method is as close to the ”native language” of the applic...

Abs t r ac t It is strongly desired to construct multimedia databases especially of maps or engineering drawings. If these databases are intended to be used really effectively, original drawing images should be recognized as completely as possible. We have been proposed a new framework of the drawing image understanding system to achieve this. This framework has following features: a) the under...
