Stroke Extraction as a Basis for Structural Analysis of Document Images by Modified MCR Expression
نویسندگان
چکیده
Since stroke components are the most basic structural featurea of patterns like ch.aracters or linea in im.ages. Prom a tiieui point of bein.g applicable to docum.en.t image understandin.g, it ia necessary to provide a good represen.tation th.at can. express such features, so th,at an interpretation of im.ages can be facilita.ted. Th.is article pre,qen.ta a new tech,n.ique used for ezpressin.g bin.ary doczim.ent im.agea. The proposed technique derieloped from the Minimum. Coverin.g Run (MCR) expression to extract stroke components of patterns in, images accurately.

Object-Oriented Method for Automatic Extraction of Road from High Resolution Satellite Images
As the information carried in a high spatial resolution image is not represented by single pixels but by meaningful image objects, which include the association of multiple pixels and their mutual relations, the object based method has become one of the most commonly used strategies for the processing of high resolution imagery. This processing comprises two fundamental and critical steps towar...

In this paper we present Document analysis and classification system to segment and classify contents of Arabic document images. This system includes preprocessing, document segmentation, feature extraction and document classification. A document image is enhanced in the preprocessing by removing noise, binarization, and detecting and correcting image skew. In document segmentation, an algorith...
متن کاملOran System: a Basis for an Arabic Ocr
In this paper we present a system for document understanding and for recognition of printed Arabic text. Arabic characters must be segmented before recognition. We overcome the problem of segmentation by our proposed ORAN system (Offline Recognition of Arabic characters and Numerals). ORAN is based on a method called Modified MCR. Using a stroke index, we can parse compound document images into...
متن کاملThe challenge of getting a high quality of RNA from oocyte for gene expression study
The extraction of intact RNA from oocyte is quite challenging and time-consuming. A standard protocol using commercial RNA extraction kit, yields a low quantity of RNA in oocytes. In the past, several attempts in getting RNA for gene expression study ended up with a few different modified methods. Extraction of high-quality RNA from oocyte is important before further downstream analyses such as...
