Knowledge-based approaches to practical image processing

Recent practical approaches to knowledge-based image processing are discussed. Three application areas are considered: document understanding, drawing understanding and industrial machine vision. The authors indicate that, in the field of document understanding and drawing understanding, the capability of real-time processing is not generally a critical problem. Therefore, a complicated systematized inference mechanism can be utilized for knowledge-based processing. However, in the industrial machine vision field, real-time processing is essential. As knowledge-based processing usually poses a great problem in its processing speed, it must be executed in a highly simplified manner
