Time-Frequency Signal Synthesis and Its Application in Multimedia Watermark Detection
<p/> <p>We propose a novel approach to detect the watermark message embedded in images under the form of a linear frequency modulated chirp. Localization of several time-frequency distributions (TFDs) is studied for different frequency modulated signals under various noise conditions. Sm...
