We propose a statistical technique of zone finding for the class of documents that are neither rigidly structured like tax forms nor very unstructured like magazine pages or engineering drawings. Given an initial window assumed to contain the final zone (bounding box) of interest, and a ‘signature’ of the target, we propose to locate the final zone by a combination of simple outside in and insi...

An integrated Multimedia CAI system of Engineering Drawing is working in Guangdong University of Technology. It includes a set of multimedia software of a teaching system, exercise system, test system, management system of Engineering Drawing and a Computer Graphics instruction system that was developed by the research group of the Department of Engineering and Computer Graphics. More than ten ...

Engineering drawings are ubiquitously used for capturing, conveying and archiving innovative engineering designs. Many engineering companies’ core intellectual property resides in their proprietary engineering drawings. Therefore, protection of such vital data is extremely important. This paper provides a swap-transformation matrix based approach to scramble engineering drawings in order to ena...

2. "Engineering design" as an activity produces an "engineering design" as a product. This product is a representation of the physical product to be manufactured and is variously called the "design object", the "product model", or after the media the "engineering drawing." Since a craftsman is only as good as his tools, the quality of the design tools (e.g., representations, conventions, and ap...

Identification of the factors affecting teaching quality of engineering drawing and interaction between them is necessary until it is determined which manipulation will improve the quality of teaching this course. Since the above issue is a Multi-Criteria Decision Making (MCDM) problem and on the other hand, we are faced with human factors, the Fuzzy DEMATEL method is suggested for solving it. ...
