The real time biometric systems are used to authenticate persons for various applications. In this paper, we propose an efficient VLSI architecture for fingerprint recognition using O2D-DWT architecture and modified CORDIC-FFT. The O2D-DWT architecture is designed using only adders and shifters for high speed operation and is applied on fingerprint image to generate four sub-bands. The optimized Fast...
The Multiplier plays an important role in implementing real time Biometric systems, hence high speed with error free multipliers has to be designed. In this paper we propose FPGA based Recursive Error Free Mitchell Log Multiplier for image Filters. The 2×2 Mitchell log multiplier is considered and error correction term is introduced to correct error, to obtain 2×2 Error Free Mitchell Log Multiplier...
