A Set of Features Extraction Methods for the Recognition of the Isolated Handwritten Digits

Abstract

Abstract-In this paper we present an off line system for the recognition of the isolated handwritten digits. The study is based mainly on the evaluation of neural network performances, trained with the gradient back propagation algorithm and fed by several feature vectors. The used parameters to form the input vector of the neural network are extracted on the binary images of the digits by several methods: the distribution sequence, sondes application, the Barr features, The central moments of image coding according to the directions of Freeman, and the centred moments of the different projections and profiles.
