International audienceIn document image analysis, segmentation is the task that identifies the regions of a document. The increasing number of applications of document analysis requires a good knowledge of the available technologies. This survey highlights the variety of the approaches that have been proposed for document image segmentation since 2008. It provides a clear typology of documents and of document image segmentation algorithms. We also discuss the technical limitations of these algorithms, the way they are evaluated and the general trends of the community

International audienceIt is very easy to ensure the authenticity of a digital document or of a paper document. However this security is seriously weakened when this document crosses the border between the material and the digital world. This paper presents the beginning of our work towards the creation of a document signature that would solve this security issue. Our primary finding is that current state of the art document analysis algorithms need to be re-evaluated under the criterion of robustness as we have done for OCR processing

As mobile document acquisition using smartphones is getting more and more common, along with the continuous improvement of mobile devices (both in terms of computing power and image quality), we can wonder to which extent mobile phones can replace desktop scanners.
