Cursive word recognition based on interactive activation and early visual processing models

Int J Neural Syst. 2008 Oct;18(5):419-31. doi: 10.1142/S0129065708001683.

Abstract

We present an off-line cursive word recognition system based completely on neural networks: reading models and models of early visual processing. The first stage (normalization) preprocesses the input image in order to reduce letter position uncertainty; the second stage (feature extraction) is based on the feedforward model of orientation selectivity; the third stage (letter pre-recognition) is based on a convolutional neural network, and the last stage (word recognition) is based on the interactive activation model.
