Kunczik, Janosch Pereira, Carina Barbosa Zieglowski, Leonie Tolba, René Wassermann, Laura Häger, Christine Bleich, André Janssen, Heike Thum, Thomas Czaplik, Michael Signal fusion algorithm for motion-based vitals assement Performance of the signal fusion algorithm on real video data. Positions of distinctive feature points are tracked over time, using the KLT algorithm. The positional (X,Y) signals are projected onto the direction of their largest movement, using a principle component analysis (PCA). The resulting signals are again fused using a PCA.
