B. V. Dhandra, Shashikala Parameshwarapa, Gururaj Mukarambi . Kannada Handwritten Vowels Recognition based on Normalized Chain Code and Wavelet Filters. National Conference on Recent Advances in Information Technology. NCRAIT, 4 (February 2014), 21-24.
In this paper, an algorithm is designed to recognize the handwritten Kannada vowels based on shape features such as normalized chain codes and wavelet filters. A normalized chain code and wavelet decomposition co-efficients are extracted as a feature vector of size 22 from the normalized binary images of size 40x40 and KNN classifier is applied for classification of vowels. A sample of 1400 Kannada vowels image are used for experiment. The average recognition accuracy of the proposed algorithm is 95. 07% for Kannada vowels.
