Abstract:
The span of writer identification extends to broad
domes like digital rights administration, forensic expert decisionmaking
systems, and document analysis systems and so on. As the
success rate of a writer identification scheme is highly dependent
on the features extracted from the documents, the phase of
feature extraction and therefore selection is highly significant for
writer identification schemes. In this paper, the writer
identification in Malayalam language is sought for by utilizing
feature extraction technique such as Scale Invariant Features
Transform (SIFT).The schemes are tested on a test bed of 280
writers and performance evaluated

Abstract:
This paper presents a writer identification scheme for Malayalam documents. As the accomplishment rate of a scheme is highly dependent on the features extracted from the documents, the process of feature selection and extraction is highly relevant. The paper describes a set of novel features exclusively for Malayalam language. The features were studied in detail which resulted in a comparative study of all the features. The features are fused to form the feature vector or knowledge vector. This knowledge vector is then used in all the phases of the writer identification scheme. The scheme has been tested on a test bed of 280 writers of which 50 writers having only one page, 215 writers with at least 2 pages and 15 writers with at least 4 pages. To perform a comparative evaluation of the scheme the test is conducted using WD-LBP method also. A recognition rate of around 95% was obtained for the proposed approach
On-line handwriting recognition has been a frontier
area of research for the last few decades under the purview of
pattern recognition. Word processing turns to be a vexing
experience even if it is with the assistance of an alphanumeric
keyboard in Indian languages. A natural solution for this
problem is offered through online character recognition. There is
abundant literature on the handwriting recognition of western,
Chinese and Japanese scripts, but there are very few related to
the recognition of Indic script such as Malayalam. This paper
presents an efficient Online Handwritten character Recognition
System for Malayalam Characters (OHR-M) using K-NN
algorithm. It would help in recognizing Malayalam text entered
using pen-like devices. A novel feature extraction method, a
combination of time domain features and dynamic representation
of writing direction along with its curvature is used for
recognizing Malayalam characters. This writer independent
system gives an excellent accuracy of 98.125% with recognition
time of 15-30 milliseconds

Abstract:
This paper presents an efficient Online Handwritten
character Recognition System for Malayalam Characters
(OHR-M) using Kohonen network. It would help in
recognizing Malayalam text entered using pen-like devices. It
will be more natural and efficient way for users to enter text
using a pen than keyboard and mouse. To identify the
difference between similar characters in Malayalam a novel
feature extraction method has been adopted-a combination of
context bitmap and normalized (x, y) coordinates. The system
reported an accuracy of 88.75% which is writer independent
with a recognition time of 15-32 milliseconds
