+* Contest
+Document Analysis Algorithm Contributions in End-to-End Applications
+
+* Description
+This contest aims to provide a metric giving indications on the
+influence of individual specific document analysis tools to overall
+end-to-end applications. Contestants are provided with a full, working
+pipeline operating on a raw document page image and proceeding to
+extract some final information. The pipeline is built with clearly
+identified analysis stages (e.g. binarization, skew detection, layout
+analysis, OCR ...) that have a formalized input and
+output. Contestants are invited to contribute their own algorithms as
+an alternative to one or more of the initially provided stages and
+evaluation will be done on the overall impact of the contributed
+algorithm to the final (end of pipeline) result.

+* Contest
+Handwritten Document Image Binarization Contest
+
+* Description
+In H-DIBCO 2010 (Handwritten Document Image Binarization Contest), the
+general objective is to record recent advances in handwritten document
+image binarization using established evaluation performance
+measures. We will create a benchmarking dataset that is representative
+of the potential problems which are challenging in the binarization
+process and use a common evaluation platform in order to test and
+compare the submitted algorithms for handwritten document image
+binarization.

+* Contest
+Historical Document Layout Analysis Competition
+
+* Description
+This paper presents an objective comparative evaluation of layout
+analysis methods for scanned historical documents. It describes the
+competition (modus operandi, dataset and evaluation methodology) held
+in the context of ICDAR2011 and the International Workshop on
+Historical Document Imaging and Processing (HIP2011), presenting the
+results of the evaluation of four submitted methods. A commercial
+state-of-the-art system is also evaluated for comparison. Two
+scenarios are reported in this paper, one evaluating the ability of
+methods to accurately segment regions and the other evaluating the
+whole pipeline of segmentation and region classification (with a text
+extraction goal). The results indicate that there is a convergence to
+a certain methodology with some variations in the approach. However,
+there is still a considera-ble need to develop robust methods that
+deal with the idiosyn-crasies of historical documents.
