Investigating the Various Approaches towards Handwritten Digit Recognition

Mr. Prashanth Kambli, Ms. Amruthalakshmi


Pattern recognition plays a vital role due to demand in artificial intelligence in practical problem. One of the problem is, that the machine faced problem in handwritten digit recognition. To recognize the digits, different features are considered such as style, orientation, curve, size, edge, thickness of the digit. Based on these factors they classifies the digits. This paper describes the different approaches that where followed to recognize the Handwritten digits. And the discussion about the different algorithms used. There are two steps involved, one is feature extraction for that there are many feature extraction methods available like, Linear Binary Pattern, Histogram Oriented Graph, Convolutional Neural Network and many more algorithms. Another one is feature classification for that many machine learning methods available like Support Vector Machine, K Nearest Neighbor so on. The main objective of all these approaches is to improve the prediction accuracy. So our main intention is to find the most appropriate method which could give highest prediction rate. In order to obtain that we created a comparative table, which compares with respect to classification method, feature extraction method, accuracy, purpose, pros and cons. Also plotted graph to compare them.
