Invertible Tansformations

  • suppose you have an orthonormal (orthogonal and unit length) basis set of vectors {}
  • Any data signal represented by a set of samples organized into a vector v can be represented by a weighted sum of the basis vectors as follows:
  • To calculate the weights do the following:
  • The vector of weights is referred to as the transformation of the signal vector v
