Abstract

Simpler methods of feature extraction and better accuracy have always been primary needs of a handwriting recognition system to be a successful real-time system. The novelty of this paper lies in the introduction of two unique methods of feature extraction which are Pixel Moment of Inertia (PMI) and Delta Distance Coding (DDC). PMI absorbs angular variations in the samples and DDC performs précised local curve coding for better recognition accuracy. Multiple Hidden Markov Model (MHMM) has been used to neutralize the effect of two very frequent writing styles of numerals “4” and “7” on their recognition rates. The paper uses MNIST database, and overall recognition accuracy of 99.01% has been achieved.
