A study by the universities of Cordoba and Seville develops a method that makes it possible to verify, easily and quickly, ...

No image is infinitely sharp. For 150 years, it has been known that no matter how ingeniously you build a microscope or a ...

Using an algorithm they call the Krakencoder, researchers at Weill Cornell Medicine are a step closer to unraveling how the ...

Abstract: In this paper, a novel 3D image file encryption algorithm based on a new discrete chaotic system is presented. Chaotic characteristics of the novel chaotic system are analyzed by phase ...

and give the image restoration probability under different oversampling rates and prior information by constructing noisy spectrum information data. The effectiveness of the algorithm has potential ...
