چکیده

This paper is focused on the study of skeleton transformations involved in the hand printed & handwritten documents’ images preprocessing. A new homotropic transformation structural element is proposed in order to optimize the sequential thinning procedure: reduced number of thinning cycles and less coarse skeleton lines. Key-Words: Hand-written Character Recognition, homomorfic transformation, Java Programming.

Preprocessing Using Structuring Element for Handwriting and Hand Printed Document Analysis

In this work we use of an optimized homotropic transformation structural element in order to improve the preprocessing stage for handwriting and hand printed document analysis. The homotropic transformation is use to improve the sequential thinning procedure. In that case we produce less coarse skeleton lines with a reduced number of thinning cycles. If the documents are not good enough, an ada...

Texture Primitive Description Using Skeleton

A novel method of texture primitive description using morphological skeleton is proposed. The skeleton of an object has the property that it is reduced to one point when the structuring element used for the skeletonization is exactly homothetic to the object. This method applies this property. This method minimizes the number of pixels contained in the skeleton. If we assume that the texture is...

Recovering dynamic information from static handwriting

-It is generally agreed that the advantage of on-line character recognition methods with respect to off-line ones mostly relies on the availability of dynamic information. This mainly concerns the order in which the strokes forming characters have been drawn. In this paper we present and discuss a method which attempts, in the off-line case, to recover part of the lost script dynamics. The meth...

Isolated Persian/Arabic handwriting characters: Derivative projection profile features, implemented on GPUs

For many years, researchers have studied high accuracy methods for recognizing the handwriting and achieved many significant improvements. However, an issue that has rarely been studied is the speed of these methods. Considering the computer hardware limitations, it is necessary for these methods to run in high speed. One of the methods to increase the processing speed is to use the computer pa...

A Radical Approach to Handwritten Chinese Character Recognition Using Active Handwriting Models

This paper applies active handwriting models (AHM) to handwritten Chinese character recognition. Exploiting active shape models (ASM), the AHM can capture the handwriting variation from character skeletons. The AHM has the following characteristics: principal component analysis is applied to capture variations caused by handwriting, an energy functional on the basis of chamfer distance transfor...
