Efficient Pre Processing Image Filter For Multimodal Biometric System

In the field of Multimodal Biometric System, the pre - processing plays a vital role in enhancing the authenticate and reliable biometric system. This paper introduces an efficient pre-processing image filter for multimodal biometric system. The proposed filter is designed to address the challenges of multimodal biometric system aiming to optimize the quality and consistency of images. The proposed filter is combination of Bilateral and Gaussian filter along with quantized histogram. The filter focuses on noise reduction, artifact removal, and enhanced resolution, ensuring that the further feature extraction, feature fusion and authentication process efficiently.
