Abstract: In embedded system, the speed of sweep fingerprint sequences stitching is very important. This paper proposes a fingerprint sequences algorithm, based on motion estimation and minimum mean absolute error. The algorithm ensures effective fingerprint stitching, reduces complexity, and improves its efficiency. Performance on simulated and real system is presented. Results illustrate the efficiency of the algorithm that is suitable for embedded system.
