Snapshot Navigation in the Wavelet Domain

wavelet coefficients to deriving a bearing and we will combine orientational features from different levels, which will add more energy from the lower frequencies
which contain important information [31]. Finally, wavelets could be combined
with an infomax learning rule [2] or a neural network (NN) trained to recall the
route [23]. Alternatively, they could be used as the input to a biologically plausible network such as a mushroom body model [1]. As wavelets can be seen as
analogous to the processing performed in the early stages of vision, optimising
the wavelet coefficients or type for different NNs could not only improve navigation performance in robots but also shed light on aspects of the visual processing
in insects.
