TLDR
This paper attempts to use the fuzzy concept on handwritten numerals and Tamil characters to classify them as one among the prototype characters using a feature called distance from the frame and a suitable membership function.Abstract:Â
The theory of fuzzy set provides an approximate but effective means of describing the behavior of ill-defined systems. Patterns of human origin like handwritten characters are to some extent found to be fuzzy in nature. It is decided to use fuzzy conceptual approach effectively in this paper. In fact, in this paper, we attempt to use the fuzzy concept on handwritten numerals and Tamil characters to classify them as one among the prototype characters using a feature called distance from the frame and a suitable membership function. The unknown and prototype characters are preprocessed and considered for recognition. The algorithm is tested for about 250 samples for numerals and seven chosen Tamil characters and the success rate obtained varies from 76% to 94%.read more

On recognition of handwritten bangla characters
TL;DR: In this paper, features are obtained by computing local chain code histograms of input character shape and the classification results are obtained after down sampling the histogram feature by applying Gaussian filter in both these cases.

Offline Handwritten Character Recognition of Gujrati script using Pattern Matching
TL;DR: This study proposes a novel solution for performing character recognition in Gujrati, the official language of Gujarat by proposing a method called Pattern Matching where a character is identified by analyzing its shape and comparing its features that distinguish each character.

R. J. Kannan,R. Prabhakar +1 more
TL;DR: This study proposes a novel solution for performing character recognition in Tamil using octal graph conversion for recognizing off-line handwritten Tamil characters which improves the slant correction and indicates that the approach can be used forCharacter recognition in other Indic scripts as well.

A Computational Approach to Edge Detection
TL;DR: There is a natural uncertainty principle between detection and localization performance, which are the two main goals, and with this principle a single operator shape is derived which is optimal at any scale.
