RANDOMIZED SIGNAL TRANSFORMS AND THEIR APPLICATIONS.
Application 572/DEL/2005 published 2006-11-10, filed 2005-03-16
Techniques are disclosed to provide randomized signal transforms and/or their applications. More particularly, a signal (e.g., an audio signal, an image, or a video signal) is transformed by applying randomly-selected basis functions to the signal. The applications of the randomized signal transforms include, but are not limited to, compression, denoising, hashing, identification, authentication, and data embedding (e.g., watermarking).
