Two remote sensing image encryption algorithms based on the randomness of audio channel sequences are proposed and their robustness is verified by many attack experiments. The first algorithm uses to encrypt pixels in RMD. Compared with traditional algorithms, this has high security can resist stronger password attacks. However, takes a long time. Considering that information sometimes needs be...

Overcomplete transforms, like the Dual-Tree Complex Wavelet Transform, offer more flexible signal representations than criticallysampled transforms. Large numbers of transform coefficients can be discarded without much reconstruction quality loss by forcing compensatory changes in the remaining coefficients. We develop and demonstrate a new and unique system for achieving these transform coding...

Deep neural networks (DNNs) have been shown to be vulnerable against adversarial examples (AEs), which are maliciously designed cause dramatic model output errors. In this work, we reveal that normal (NEs) insensitive the fluctuations occurring at highly-curved region of decision boundary, while AEs typically over one single domain (mostly spatial domain) exhibit exorbitant sensitivity on such ...
