In this paper we present a new hybrid page segmentation approach based on connected component and region analysis. We first describe our stroke descriptor that detects text and line component candidates using the skeleton of the binarized document image. Then, the active contour Chan and Vese model is applied to segment the rest of the image into photo and background regions. This classificatio...

A persistent flaw in the evaluation of page segmentation algorithms is examined.

Page stream segmentation (PSS) is the task of retrieving boundaries that separate source documents given a consecutive (for example, sequentially scanned PDF files). The has recently gained more interest as result digitization efforts various companies and organizations, they move towards having all their available online for improved searchability accessibility users. current state-of-the-art ...

Empirical performance evaluation of page segmentation algorithms has become increasingly important due to the numerous algorithms that are being proposed each year. In order to choose between these algorithms for a speciic domain it is important to empirically evaluate their performance. To accomplish this task the document image analysis community needs i) standardized document image datasets ...

This corrects the article "Changes in Shape of Combination a One-Length Cut and Medium-Graduation according to Segmentation Head Regions Slice Lines" on page 221.

Given a set of handwritten documents, a common goal is to search for a relevant subset. Attempting to find a query word or image in such a set of documents is called word spotting. Spotting handwritten words in documents written in the Latin alphabet, and more recently in Arabic, has received considerable attention. One issue is generating candidate word regions on a page. Attempting to definit...

ÐWhile numerous page segmentation algorithms have been proposed in the literature, there is lack of comparative evaluationÐempirical or theoreticalÐof these algorithms. In the existing performance evaluation methods, two crucial components are usually missing: 1) automatic training of algorithms with free parameters and 2) statistical and error analysis of experimental results. In this paper, w...

A top-down page segmentation technique known as the recursive X-Y cut decomposes a document image recursively into a set of rectanguzar blocks. This paper proposes that the recursive X-Y cut be implemented using bounding bozes of connected components of black pixels instead of using image pizels. The advantage is that great improvement can be achieved in computation. In fact, once bounding boxe...
