Hermite transform has been used In various signal processing applications due to many desirable properties. Particularly, when compared with the trigonometric functions, Hermite functions provide better computational localization in both signal and transform domains. Therefore, this transform has been applied in image compression, tomography, biomedical applications, etc. However, the performance...
A general form of compressive sensing (CS)-based higher order time-frequency distributions (TFDs) is proposed. Non-linear time-varying spectrum analysis requires higher order TFDs, but they cannot produce efficient result in the presence of strong noisy pulses. Consequently, the time-frequency analysis needs to be combined with the L-statistics. When applied to the higher order local auto-correlation...
A procedure for image watermarking based on the Hermite projection method is proposed. The coefficients obtained by the Hermite expansion are used for watermark embedding. In the same time, the Hermite projection method provides efficient compression approach, since the image can be recovered by using smaller number of Hermite coefficients. The efficiency and robustness of the proposed procedure is...
