Application of Smart Pixels to Optical Implementation of the Wavelet Transform
The concept of wavelets is based on fundamental ideas in transform domain processing, which were
first expressed centuries ago in a variety of forms. However,
it is only within the past decade, since the pioneering
work of Daubechies demonstrated the relationship between wavelets and subband transforms, that significant progress has been made in applying wavelet theory
to practical signal processing problems. Since then, there
has been an explosion of interest in wavelets and subband
transforms for wide-ranging applications in signal
processing, communications, biomedical techniques, and many interdisciplinary fields.
