Emerging Applications to Signal Processing
In this chapter we discuss some new applications of algebra to signal processing. The first way in which this arises is via the transfer function of a filter. This leads to questions about polynomials and rational functions, which can sometimes be solved by ideas from algebraic geometry, often with better results than through numerical methods. The second application of algebra is to image processing. We already saw how three-dimensional rotations can be simply described by quaternions – now we look at an application in face recognition.
