Gujarati language has a variety of characters which makes the language diversified.The language has a total thirty-four consonants and eleven vowels that have different shapes.The characters have features like vertical lines, vertical lines with curves, only curve, curve with one loop and curve with two loops that differentiate the characters from one other.In this paper, the researcher has used a set of consonants which only has curves.Total eight (8) consonants "ક" (k), "ટ '(Ta), "દ ' (D), "ર '(Ra), "ળ '(Al), "ફ '(Fa), "ડ '(Da) and "ઝ '(Jha) have only curve as a feature.These consonants have been taken into consideration in this research paper.For training the GHCIR system 1200 samples of each curved consonant has been collected, while the system has been tested with 100 samples of each curved consonant.The average accuracy achieved after processing for all the curved consonant is 84.25%.Further, the researcher has done the performance analysis of the Gujarati Handwritten Consonant Identification and Recognition (GHCIR) System using the Kappa coefficient.The average Kappa Coefficient justify that the system identifies all the Gujarati handwritten curved consonants with a substantial level of agreement.
