Content Based Image Retrieval System for CAD Images

Any image retrieval system that is based on the content (numeric features) and associated information of a CAD image, suffers from a problem that the unit of information is basically a numerical value and hard to interpret in terms of human understanding. Therefore, there is an urgent need to remove this barrier so that the retrieval system works for humans and with humans. This book has been written to showcase an implementation wherein access to full information relevant to a CAD image is provided, which helps the user in performing some useful technical task. The desired outcome has been achieved by reducing the semantic gap between the system and the needs of the human informational retrieval, at the same time giving high precision and recall values.
