On watermarking in frequency domain

SPIE Proceedings, 2010
A wavelet-based image watermarking scheme is proposed, based on insertion of 'logo' image as watermark in midfrequency domain. This new approach provides flexibility in determining the pixel to be watermarked and increases the data hiding capacity. It is easy to implement watermark embedding algorithm as well as the corresponding detection algorithm.

The Ultrahigh-Frequency Domain

Transactions of the American Institute of Electrical Engineers, 1937
Use of ultrahigh frequencies for educational broadcasting has been thought to offer attractive possibilities because of the supposedly almost unlimited number of channels; however, the demands of other radio services, particularly television, may be expected to congest this newly opened region. Ultrahigh-frequency waves behave somewhat like light waves,
