Abstract In astronomy, upcoming space telescopes with wide-field optical instruments have a spatially varying point spread function (PSF). Specific scientific goals require high-fidelity estimation of the PSF at target positions where no direct measurement is provided. Even though observations are available some field view (FOV), they undersampled, noisy, and integrated into wavelength in instr...

Digital watermarking is a way to provide the facility of secure multimedia data communication besides its copyright protection approach. The Spread Spectrum modulation principle is widely used in digital watermarking to satisfy the robustness of multimedia signals against various signal-processing operations. Several SS watermarking algorithms have been proposed for multimedia signals but very ...
