Content retrieval of scanned line drawing images is a difficult problem, especially from real-life large scale databases. Existing algorithms don't work well due to their low efficiency by first recognizing various types of graphical primitives and then content-oriented texts. A new method for directly detecting texts from line drawing images is proposed in(More)
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. 1 Introduction Over the past(More)
