High Capacity Reversible Watermarking for Audio by Histogram Shifting and Predicted Error Expansion

The Scientific World Journal, 2014
Being reversible, the watermarking information embedded in audio signals can be extracted while the original audio data can achieve lossless recovery.

Implementation issues in source coding [PDF]

An edge preserving image coding scheme which can be operated in both a lossy and a lossless manner was developed. The technique is an extension of the lossless encoding algorithm developed for the Mars observer spectral data.

Universal share-based two-in-one multi-image secret sharing scheme by rotating random grids

EURASIP Journal on Information Security
Multi-image secret sharing (MSS) scheme for two decoding options by employing universal share is discussed in this manuscript. One decoding option is piling of shares to get a secret image preview and the other option needs computation of shares to get a

Novel Integer Reversible Charlier Transform for Image Reversible Data Hiding Application

IEEE Access
The discrete Charlier moment transform, while extensively utilized in image processing, is inherently lossy and non-integer reversible, making it unsuitable for lossless image applications.

A New Family of Soft Single Switched DC-DC Converters with Lossless Passive Snubber

Majlesi Journal of Electrical Engineering
In this paper, a novel lossless snubber is introduced that provides ZVS conditions for both On and Off instant of converter switches. On one hand, the energy of the snubber is optimally transmitted to the output so that no significant losses are imposed ...
