Hardware design of real-time offline Jawi character recognition chip using discrete wavelet transform

ln this paper, we discuss further on our previous works (Razak, 2003) on developing a recognition chip of Jawi characters using chain code algorithm and problems occurred. An explanation of Jawi (Arabic like) characters have been made in (Razak, 2003). We also discuss our second approach i.e using discrete wavelet transform (DWT) to extract coefficients from the characters based on their features and using these coefficients to develop a unique code. This unique code was used to recognize it. Hardware model entities integration is presented in the last section. Paper orientation was like this. First we discuss on why we choose DWT & way to implement it and followed by the problems we faced in using chain code algorithm. The full implementation of the design was explained in the last section, followed by a conclusion
