Abstract

The human eye recognizes familiar shapes despite all changes and distortions found in the retinal images. In this paper, the handwritten character recognition system using fuzzy wavelet is modelled using VHDL. The fuzzy wavelet handwritten recognition is a system based on human perception. The time-frequency localization capabilities of wavelet transform in feature extraction enhances the accuracy of recognition at pixel level. The characteristic features of handwritten character in image format are extracted by taking Haar wavelet transform. The design was implemented using Very High Speed Hardware Description Language (VHDL). The VHDL model is simulated and synthesized using Altera's Quartus II. The system operates up to 13.27 Mega Hertz (MHz) with equivalent longest propagation delay of 75.336ns. Total of 7183 Adaptive Look-Up Table (ALUT) s, 152 pins and 63 DSP block 9-bit elements are used to implement this VHDL model.
