This paper presents a method for vectorizing the graphical parts of paper-based line
drawings. The method consists of separating the input binary image into layers of …

We present a document analysis system able to assign logical labels and extract the reading
order in a broad set of documents. All information sources, from geometric features and …

We describe an approach for table location in document images. The documents are
described by means of a hierarchical representation that is based on the MXY tree. The …

Many novice programming environments use puzzle-like approaches to help novice
programmers acquire new programming skills independently. Yet, little is known about 1) …

This paper introduces the concept of location-based publish/subscribe (LPS), which allows
mobile ad hoc applications to anonymously communicate with each other, depending on …

This paper describes an algorithm for the determination of zone content type of a given zone

In this paper we present a top-down, projection-profile based algorithm to separate text
blocks from image blocks in a Devanagari document. We use a distinctive feature of …

As a universal technical language, mathematics has been widely applied in many fields, and
it is more accurate than any other languages in describing information. Therefore, numerous …
