Tight Frames and Dual Frame Pairs
2016We have already highlighted the frame decomposition, which shows that a frame \(\{f_{k}\}_{k=1}^{\infty }\) for a Hilbert space \(\mathcal{H}\) leads to the decomposition $$\displaystyle\begin{array}{rcl} f =\sum _{ k=1}^{\infty }\langle f,S^{-1}f_{ k}\rangle f_{k},\ \ \forall f \in \mathcal{H};& &{}\end{array}$$ (6.1) here \(S: \mathcal{H ...

The angle preserving transformations of \(\mathbb {R}^2\) form the real orthogonal group $${ O}(2) := \{A\in \mathbb {R}^{2\times 2}:A^T A=I\},$$ which can be thought of as the symmetries of the inner product space \({\mathscr {H}}=\mathbb {R}^2\).
