An algorithm for real-time implementation of affine frames generated by 'oversampling' is introduced. This notion of oversampled frames differs from the more well-known concept of over-sampling in that no extra data information is required in the implementation of our oversampled frame algorithm. The advantages of this fast-frame algorithm over the standard wavelet decomposition algorithm in signal processing include its ability to reduce the destructive effects due to aliasing and the presence of uncorrelated noise, as well as to compensate for the lack of shift-invariance in discrete wavelet decomposition.
