Compressimo

Product
Developers: Cognitive Technologies (Cognitive technologies)
Last Release Date: September, 2012
Technology: EDMS - Systems of stream recognition

The Russian company Cognitive Technologies brought in the summer of 2012 to Russian and the foreign markets the Compressimo program intended for scanning and compression of documents and their transfer by mail.

Developers of a product managed to solve the problem, major for electronic document management, – to provide a high compression ratio of the digitized documents at high-quality preserving of the archive copy. According to the Head of Department of mass input of documents Vladimir Arlazarov, standard shrinking algorithms of the digitized images are a little applicable for this purpose – they can provide high quality of the document only at its preserving in the form of quite volume file.

The Cognitive Technologies company developed own algorithms of processing of the scanned documents. Last year the technology of a compression of Cognitive PDF/A which solves a problem of compact preserving of images due to structural analysis as in space of subjects of the document (the text, pictures, signatures), and in color space (color, bitonalny texts) was provided. On the basis of histograms of color saturation of the image are separated into the zones containing the text, and zones with not text objects. Besides, it is taken into consideration that in color space the black-and-white text is in a certain zone, and all color objects – in other zones. Thanks to it in the document the text layer and a layer with printings, signatures, etc. are selected, in each of them the indicators can be set to contrast and saturation, at the same time the bitonalny text can be subjected to considerable compression, providing at the same time its good readability, and a layer with printings and signatures to squeeze to a lesser extent.

After assembly of all layers it is possible to reduce considerably volumes of final files in comparison with what traditional methods give. For example, the normal consignment note of A4 format with printings and signatures after scanning with the resolution of 300 dots per inch and preserving in the JPG format with compression of 90% occupies about 1 MB whereas Compressimo packs it into the file of the PDF/A format with a capacity of 90-100 Kb, and sometimes and it is less of that. 90% of document flow of the Russian companies are the share of a share of such documents (laid on, business letters, accounts, agreements, receipts, tables) usually.

At document handling the Compressimo program quite often possible to receive a text layer of the best quality, than in the initial document. The program provides text recognition in 23 languages using the built-in it and modifed kernel of the CuneiForm OCR system (Cognitive OpenOCR). The company opened source codes of the last in 2008, and since then using the new participants who joined the project it was considerably improved. The recognized text remains together with the image of the document that provides a possibility of full-text search and text copying. It should be noted that other methods of image compression do not provide such opportunity. Besides, the resulting documents created by the Compressimo program in the PDF/A format completely conform to requirements of ISO 19005-1:2005.

According to the director of international sales Anton Nazarkin, from the moment of Compressimo output to the Russian market in June, 2012 more than 3500 licenses are sold already. At the same time the program is expected a wide range of users, does not require preset tunings and is so simple that any clerk can master it in several minutes. The small size of the processed files allows to have big archive of electronic documents in online access, and the enterprises with pleasure refuse paper documents: at once scan them and hand over in archive from where take only in special cases, for example upon the demand of court, etc. Cognitive Technologies expects to win in three years 7–10% of the world market of the systems of scanning and compression of documents which volume experts predict at the level of $20 billion.

The 30-day full-function demoversion of the program can be downloaded from the website www.compressimo.ru. We seized this opportunity and checked: the file of the consignment note with printings and signatures saved after scanning with the resolution of 300 dots per inch in the JPG format with compression of 90% occupied 1.24 MB; the same document saved by the Compressimo program in the PDF/A format – 93 Kb.

The cost of the license Compressimo for one workplace is in Russia 799 rubles, in foreign market – 20 euro. Views: 247
