| Abstract: | Aiming at the problem of surrogate exam-takers and cheating at examinations,the paper presents hardware framework based on ARM and DSP. After triangulation of fingerprint minutiae,the minutiae points are quickly searched by triangle indexing,and the candidates for an examination are identified through the fingerprint identification technology x264 open source algorithm is used to handle the video,and thus implement a close watch of exam room. |
