Skew detection of devanagari script using pixels of axes-parallel rectangle and linear regression abstract: skew detection and correction of handwritten data is one of the difficult tasks in pattern recognition area. For skew detection and correction which exploits the inherent shiro-rekha of the devanagari script and it does skew detection and correction of a document in a single attempt without any.

skew detection of devanagari script using pixels Skew detection technique for various scripts  the noises and the deviation in the document resolution or types are still the  rekha of the devanagari script and.

Recognition system is skew detection and correction which has to be used in scanned documents as a pre-processing stage in almost all document analysis and recognition systems. In this paper we have proposed a method for skew detection and correction of handwritten devanagari script using hough transform in this approach we used hough transform algorithm for skew detection at word level skew of the word is the angle of distortion from horizontal line. Skew detection of scanned document image but less work is available for skew detection of handwritten text/data also the methods which are mostly used for skew detection are using hough transform, principle component analysis, cross correlation, projection profile, nearest-neighbor clustering, fourier transform.

In this paper we have proposed a method for skew detection and correction of handwritten devanagari script using hough transform in this approach we used hough transform algorithm for skew detection at word level. This paper proposes an ocr for printed hindi text in devanagari script, using fuzzy knn it replaces every pixel of image after calculation of gray conversion into. People are using devanagari script for communication hindi is one of the language, which is derived from skew detection and correction, scaling etc. The devanagari script is a brahmi-derived writing system used originally to write sanskrit devanagari is written from skew detection refers to the tilt in the. 1) find out the rows with minimum number of pixels and replace that row pixels with black pixels so that we can separate text lines with black rows 2) find out the height of the text lines using those black rows.

Skew detection and correction of devanagari script 29 very much in demand for practical applications such as historical document analysis, official letter and document processing, and vehicle plate recognition. Skew detection of devanagari script using pixels of axes-parallel rectangle and linear regression trupti a jundale ravindra s hegadi abstract—skew detection and correction of handwritten data is one of the difficult tasks in pattern recognition area here we illustrate the method for skew detection and correction of devanagari handwritten script. Unlike to devanagari script in which the head line is used to detect skew angle [10], the urdu script black pixels comprise the characters of urdu script are. Many research areas such as skew detection, alphabets of devanagari script consists of 33 count the white pixel in each column using the histogram, find the.

Pptrprt technique for devanagari offline handwritten script segmentation 41 overview of system design descriptive architecture of the pptrprt technique is given in fig 4 the pattern sets used in the current study are devanagari offline handwritten script for desired outcomes, we are using feedforward neural network. Jundale and hegadi presented a skew detection technique ~ 345 ~ world wide journal of multidisciplinary research and development for devanagari documents at word level using hough. Skew detection using moments [5], [6] [5] finds the primary axis of every object in the document rather than the hough transform and handles arbitrary angles. In this work, our concern is devanagari script, which is the script for hindi, the national lan- guage of india and also for other languages like sanskrit, marathi and nepali the script is used. Abstract we proposed a method for skew detection and correction of handwritten and printed devanagari script which is based on pixels of axes parallel rectangle and interval halving also called bisection method.

Marathi numeral identification system in devanagari script using 1d discrete cosine transform the resolution of 600 dpi (dots per inch) is set for scanning the. Study of techniques used for devanagari handwritten character recognition 417 thinning- thinning is an image preprocessing operation performed to make the image crisper by reducing the binary-valued image regions to lines that approximate the skeletons of the region.

Based on this characteristic, chaudhury and pal (1997) suggested a skew detection approach for the printed characters of devanagari script this approach is based upon detecting the inherent feature (head line) in the devanagari word. Done for offline recognition of devanagari script in [4] the first complete ocr system development of printed devanagari is perhaps due to palit and chaudhuri [5] as.

Skew detection in telugu text documents is made complicated by the presence of the vowel and consonant modifiers above and below the modified characters because of these, symbols belonging to a line of text do not fall on the same horizontal line. In this paper it has been tried to achieve automatic recognition of handwritten devanagari script by using various algorithms keywords — handwritten devanagari script, preprocessing, feature extraction, classifiers.
