Dynamic multiple-image encryption based on chirp z-transform
(IOP Publishing, 2019-02)
It is demonstrated a dynamic encryption scheme based on chirp − z transform (CZT). The novel design of this setup allows to protect multiple images in a multiplexed format and fully recover them without the influence of ...
A new concept of Compton Scattering tomography and the development of the corresponding circular Radon transform
(Institute of Electrical and Electronics Engineers, 2019-09-24)
A new modality of Compton Scattering Tomogra-phy is presented. This model is composed of a fixed sourceand detectors placed on a fixed ring passing through thesource. This new modality, called Circular Compton Scattering ...
An image analysis study of pit formation on Ti-6Al-4V
(Elsevier B.V., 2003-01-20)
Metallographic techniques and digital image processing have been used to investigate heat-treated Ti-6Al-4V pitting corrosion, often used as aircraft components. LM and SEM metallography of 'as received', annealed (heating ...
