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...
The authentication of a person using bimodal biometric is robust and accurate compared to single biometric traits. In this paper we propose Dual Transformation Bimodal Biometrics Based on Feature Level Fusion (DBFLF). The Fingerprint and Face of each person is considered to identify a person. The fingerprint is preprocessed to obtain Region of Interest (ROI). The DTCWT is applied on ROI of fingerprint...
The Fingerprint is used to authenticate a person for multiple applications. In this paper, we propose Fingerprint Verification Based on Dual Transformation (FVDT). The Fingerprint image size of 300∗480 is segmented into four cells of each size 150∗240. The DCT is applied on each cell to convert from spatial domain to frequency domain. One level DWT is applied on DCT coefficients to derive four sub...
The Fingerprint is widely used biometric to identify and authenticate a person in the society. In this paper we propose Fingerprint Recognition using Inter Ridge Variation (FRIRV) algorithm. The finger print is segmented into 8*8blocks and variance of each block is determined. The threshold value is fixed to remove minimum variance blocks to get Area of Interest (AOI). Discrete Cosine Transform (DCT)...
