An overview of strategic workflow design to develop multimodal biometric recognition systems

It has been a proven fact that the inclusion of more than one modality makes biometric recognition systems more robust and elevates its recognition accuracy. This paper aims to develop a strategic platform for the upcoming researchers in order to develop multimodal biometric recognition systems. The researchers in this fraternity would be able to design their own procedural strategy using the generalized workflow template depicted in this review. The selection of proper visually interpreted biometric identifiers and modalities, various fusion strategies, choice of performance metrics, formation of training and test sets from databases and the possible challenges in developing the workflow are purposefully portrayed in this article.
