Chirp transform

Webpaper the ‘‘fast chirp transform’’ FCT . The techniques discussed in this paper appear to be re-lated to filter bank design, to wavelet analysis, and to STFT’s. In fact, the chirp transform can be viewed as a pre-scription for coherently adding the outputs of a bank of variable-length STFT’s with a particular time-domain rela ... Webthis study, we propose a chirp-based detection method to de-tect watermark messages in an image watermarking scheme [3][4] which embeds linear chirps as imperceptible and sta-tistically undetectable watermark messages. Different chirp rates, i.e., phases, represent watermark messages such that each phase corresponds to a different message. The ...
